Genealogy Testing

Genealogy is a field of study to learn a person’s family history. Genealogy testing refers to DNA testing that involves using genetic DNA information to determine the lineage and pedigree of a person. Also known as genetic ancestry testing, genealogy testing includes examining and evaluating a person’s DNA variations to find clues that link them back to their ancestors.

Genealogy Testing

Genealogy tells a person about their lineage and ancestors and helps to find distant relations that might be somewhere in another part of the world like 3rd, 4th, and 5th cousins. Besides that, people with the same backgrounds can also share various genetic variation patterns.

What is Genealogical DNA Testing?

Genealogical testing is a DNA-based testing method. It focuses on the particular location of a genome in a person. This is because it helps in discovering and proving the ancestral relationships of a person. While all this information may sound complex to comprehend and memorize, the actual studies and scientific data are way more complicated than this.

Genealogical testing also allows experts to locate a person’s genome to determine their mix of ethnicities. Since old races and ethnicities populated different regions, migrated, and varied greatly, the estimates are merely a close assumption based on the present data.

Moreover, companies that perform ethnicity testing use different testing techniques and methods, which can cause relative variations in the test results. For genealogical testing, there are three fundamental forms of genealogical studies.

Types of Genealogical Testing

·       Autosomal Testing

Autosomal DNA testing yields multiple DNA matches of both females and males, considering they hired the same company for testing. Every match may depict a distant relation of some kind, including close family matches or cousins of the 1st, 2nd, 3rd degree, or more. Usually, experts regard the 6th cousin or further the most distant relationship degree. Nonetheless, making precise conclusions over close relations of individuals with each other is not so easy.

You have to realize the random nature of the tests, which suggest that any person can inherit any type and amount of DNA from their ancestors (common lineage). However, genealogical research and family-tree sharing help experts interpret the results of those test subjects whose DNAs match as close or slightly distant relations. Overall, the use of autosomal tests is to determine the ethnic mix of a person.

·       Y-chromosome Testing

Y-chromosome DNA testing can help find your lineage directly into the male line. Since y-chromosomes pass down from grandfather and father to son, there are significant variations as well. Moreover, this type of DNA testing method in genealogy only pertains to males as females do not have the y-chromosome.

Still, if a female is curious about their y-chromosome test results, they may recruit a close male relative such as a brother to take the test. What’s rather interesting is that y-chromosomes transfer from generation to generation, similar to the surnames. Hence, it can be quite helpful in learning whether two families with the same surname have an ancestral relationship.

Types of Genealogy Testing

·       Single Nucleotide Polymorphism Testing

Single Nucleotide Polymorphism (SNP or SNPs) involves evaluating nearly all the genetic variations that are present in a person’s genome. Experts compare the follow-up test results with others who have already taken the tests to estimate their ethnic background. While this complex and highly time-taking DNA-based testing can be intricate, it can give you a fair idea of your ancestral background and what ethnicity mix you are.

For instance, SNPs are effective because they determine a person’s overall ethnic (ancestral) background. You might learn that a person is 60% African, 10% Asian, and 30% European. While this still doesn’t clear an individual’s ancestral line, it gives an idea of the ethnic mix compared to the mitochondrial and y-chromosome DNA test results.

·       Mitochondrial DNA Testing

Both genders have mitochondria DNA which is somewhat the own DNA of the mitochondria other than that which is present in the center (nucleus) of the cells. While both genders have it, the mitochondrial DNA passes down only from the mother, so you might be able to determine your maternal line. It helps learn your lineage through the female ancestral line because of the female ancestors records that are near negligible in the form of documentation.

Genealogy Testing: Conclusion

Are you in the search to find your ancestral line and lineage? Genealogical DNA testing can help you learn about your distant relationships in different ethnicities and your ancestral background. If you want to get the best DNA testing services, you should contact AB DNA Testing.

DNA Testing Requirements for Immigration to the USA

Immigration DNA testing for the US can comprise maternity, kinship, or a paternity test. The main purpose of this testing is to grant approval to a visa applicant to the US who already has relatives there. Note that the US Embassy and Consulate, which deals in immigration DNA testing, doesn’t regard distant relatives as close blood relations. Therefore, the kinship should be close to your lineage and parentage, such as your uncle, grandparent, son, brother, etc.

Immigration DNA testing

This method of testing ensures high accuracy in verifying family relationships. It becomes a necessary process once there is no source of credible document or proof to verify the relationship between the visa applicant and the beneficiary. In the US, different departments may require Immigration DNA testing. They include:

  • S. Embassy
  • Department of Homeland Security
  • USCIS (U.S. Citizenship and Immigration Services)

Here’s what the Immigration DNA testing allows you to acquire in your biological relationship’s verification process.

  • Citizenship petitions
  • Immigrant Visa
  • S. passport applications

Why Would You Require DNA Testing for US Immigration?

DNA testing is the most accurate method of verifying biological relationships, especially for the immigration process. For some, passing the Immigration DNA testing can help families reunite. If the US immigration department finds any uncertainty or problem in the petition request, they may demand a DNA testing report.

This mainly occurs when a visa applicant goes for an immigration petition but doesn’t provide sufficient details and credible proof to verify their relationship with their kin in the US already. Therefore, immigrant DNA testing may be necessary to clear the information about the beneficiary and petitioner’s relationship. For countries where there aren’t credible birth certificates and several important documents, DNA testing for immigration is a must.

On the other hand, if you and your kin provide appropriate proof of your biological relationship as a petitioner or beneficiary, you may still need to pass the immigration DNA test. Staying calm in such situations is the best approach, as the test will surely pass if you aren’t committing any fraud.

Furthermore, with strict background checking and regulations, there isn’t usually any room for fraud in the immigration process. Combine that with the DNA tests, and you will have to go through a rigid immigration petition process. However, your focus should be the test results that will confirm your biological relationship with your beneficiary.

Types of DNA Sampling for Immigration

USA Immigration DNA testing services and information

While DNA testing is one of the most accurate biological relationship testing methodologies, it is now widely used for legal issues and processes. It is better and accurate than many other testing and relationship verification methods; DNA testing has various types.

The preferred technique to collect the specimen of the petitioner and/or applicant is through a buccal swab. This involves using non-invasive cotton swabs that easily collect DNA by gathering cells from the open mouth or cheek cavity.

It is the most common DNA sample collection method instead of the blood samples. This is because swabs are painless, non-invasive, comfortable, and easier to ship overseas/abroad. You should know that the DNA testing standards and reliability have crossed the average accuracy barriers by reaching matches of 99.99% accuracy. Surprisingly, the Consular officer in the US might not accept a DNA test result that has accuracy below 99.95%.

Requirements and Process of DNA Testing for Immigration to the US

The US Government and Immigration Department demand that you get DNA testing facilities and services of only AABB-accredited and certified testing labs. These are the only test results that are legally permissible. AABB accreditation requirement from the US government and Immigration office enforces higher testing standards, zero-contamination, and lower chances of inaccurate results.

These are a few simple steps that you may have to follow if the immigration office requires you or your family to provide DNA test results.

Initially, choose a DNA testing lab that is AABB-certified (American Association of Blood Banks).

The lab shall collect DNA samples of the parties involved and then perform tests with highly accurate values. Further, they will directly send the DNA kit to the US Embassy or Consulate. Upon receiving the DNA kit, the embassy will have an appointment with the applicant for their DNA sample.

The test results will directly reach the US Immigration office and the senior officials. Remember that mailing your DNA test results from home using at-home DNA testing kits will result in rejection and greater delays in the verification process.

Immigration DNA Testing: Conclusion

Being an AABB-accredited DNA testing facility, AB DNA Testing provides the most accurate & reliable DNA testing services. We offer not only DNA testing services for Immigration to and out of the US but also many other legal issues. These include paternity, maternity, and other types of DNA tests.

Without any hidden charges, we offer individualized attention to every applicant. What’s more, our experts have years of experience and knowledge in blood and DNA testing. Call us at 718-701-0292 for more information. Pay us a personal visit at 63-11 Queens Blvd. Woodside, NY 11377.

DNA & Genetics

Before understanding DNA and genetics and how they connect, you should know that the human body comprises 30,000 genes. In simple words, without genes, we wouldn’t have the genetic, physical features. Every person is different from others. It is because of the specific genes that are hereditary.

DNA & Genetics

You may resemble your other family members, perhaps your parents. However, through scientific testing, you may notice that you are different from everyone. Genes determine our physical features and characteristics, such as the shape of the nose, jaw alignment, fingerprint, head shape, height, and much more. So, we should spend a few minutes learning about DNA and genes.

What are Genes?

Genes are present in our body as part of the living cells. They comprise the most important biological information that passes from generation to generation through parentage. They are responsible for your growth and cell development. One of the main components of a gene is DNA, a biomolecule known as “deoxyribonucleic acid.” DNA contains information regarding the development of your cells and is present in the nucleus of every cell.

To understand better, you should learn that half of your genetic information comes from your father while the other half is from your mother. They combine to form the genetic traits which make your physical features. Some of these features include your eye color, hair color, and more. Also, it involves carrying the risks of certain diseases that may also pass down from generation to generation. Uncertain genetic changes (mutations) can lead to disturbance in their function and development.


In basic terms, genes define nearly everything about a living organism. It’s not just the simple physical traits but also the habits and subconscious nature that form due to genetic information. For example, impulsive spending is a habit that you may inherit from your parents. From determining the physical characteristics to the chances of developing various diseases, genes are responsible.

What is DNA?

DNA is present inside the center of a cell which is the nucleus. This is where it forms protein-carrying chromosomes that bind with the DNA known as “histones.” To begin with, DNA contains two strands that twist and form a spiral ladder structure which we refer to as a double helix. Here are the four building blocks of DNA (nucleotides):

  • Thymine (T)
  • Cytosine (C)
  • Guanine (G)
  • Adenine (A)

These building blocks permanently attach (G to C and A to T) to form base pairs inside the DNA. These base pairs connect and hold both the strands of the DNA. Following that, genes become the small pieces of DNA that carry essential and highly specific genetic information.


DNA contains cell development and growth information based on which it instructs the cells of living organisms to reproduce, develop, and function. This information stays in the base pair sequences inside the DNA. Typically, your cells read the codes on the DNA to learn the information that instructs the production of proteins that are critical for physical survival and growth.

Gene is the name given to the entire DNA sequence carrying the essential growth information. Different base pairs in the DNA produce different types of proteins and acids in the living cells. Combinations like T-G-A, T-A-A, T-A-G, and some other proteins may signify a protein sequence’s end. Hence, the DNA also contains information to stop the production of protein.

What Are the Main Types of Genetic Testing?

Here are the main types of genetic testing that consider the precise information and characteristics they form in living organisms.

Prenatal Testing

This DNA testing method ensures the health of a fetus and detects if it has a medical disorder like Down syndrome. Such test results help in guiding the vital decisions of handling the pregnancy. Learning about the medical condition of the fetus helps to maintain the health of the mother and the unborn child.

DNA & Genetics Testing

Carrier Testing

Carrier testing hints towards learning the chances and likeliness of passing down a family disease or disorder to your children. You may previously have a family disease history which can lead to disturbance in your child’s life.

Presymptomatic Testing

It measures the likeliness and chances of you carrying a genetically mutated cell or genetic change that may raise your chances of developing a certain kind of disease. Since this is predictive testing, it helps in managing health and disease prevention.

Genetic Testing

It is merely a DNA testing method to confirm a genetic condition that results in developing a disease of which you might be experiencing symptoms already.

Forensic Testing

It occurs for legal reasons such as identifying a dead body, crime-solving, establishing paternity, and so on.

DNA & Genetics: Conclusion

If you are looking for the best place to get DNA or genetic testing, you are at the right place. At AB DNA Testing, our team of experts caters to your DNA testing needs and requirements. We provide effective testing techniques and methods, whether testing for immigration, paternity, maternity, or any other legal reason.

DNA Testing: Can You Test For Ethnicity?

Is there DNA testing For ethnicity? Genetic testing is a personal decision. In fact, it is for those people who have an interest in learning their lineage through male and female ancestral lines. Although it is exciting to know your ethnic background and its mix, the decision to get the test done can be a bit confusing and complex. Nonetheless, by hiring the right DNA testing company, you will get accurate results. Bear in mind that you should consult a genetic counselor to help you learn the emotional and psychological effects of knowing your true lineage.

DNA Testing For Ethnicity

Often, people find results that are far from their expectations. Hence, it overwhelms them to know their true lineage and ethnic mix. Still, you should know that living in the present, learning about your ancestors is just about studying genealogy. Having an ancestral line that you wish you didn’t have doesn’t impact who you are today.

So, let’s get to the main question: Can you test for ethnicity?

What is DNA Testing?

Genetic testing is also DNA testing, which involves observing any changes or alterations in the proteins, genes, or chromosomes of a person. This medical test can help rule out the chances of developing a serious or acute genetic condition. Furthermore, genetic testing reveals if you have any genetic mutation that you may pass down to your children. This is important because many couples and families rely on such data to plan their pregnancies.

This is what typical genetic testing, also used for genetic ancestry testing, looks to identify:


Genetic testing can identify changes that occur in the activity levels of any enzymes or proteins. These abnormalities indicate any changes in the DNA, which might lead to the development of genetic disorders.


Genetic mutations are responsible for increasing a person’s chance of developing and experiencing genetic disorders. Experts can study these genetic mutations through gene tests that help them learn the DNA sequences of an individual.


Chromosome tests are genetic tests that analyze and evaluate the changes (if any) on the long DNA strands or entire chromosomes. Often, changes to these two features of DNA sequences and genetic order can lead to developing genetic conditions in a person.

Benefits of DNA Testing (Genetic Testing)

Why should you perform DNA testing (genetic testing), if not for legal reasons, such as immigration and determining paternity/maternity for child custody? Test results can affect the level of comfort and relief a person might have. In case of suspecting a disease through genetic disorders, a negative test report might relieve the individual. What’s more, they may not require additional checkups and incur unnecessary health care expenses.

On the other hand, positive test reports can guide a person toward better prevention and treatment options after learning about their present genetic conditions. Genetic testing helps people make informed decisions. Importantly, newborn screening tests (genetic testing) can help identify any underlying genetic conditions in an infant. Hence, people can begin early treatment right from the start.

DNA Testing for Ethnicity: DNA Testing Types to Reveal Your Ancestry

·       Y-chromosome

Y-chromosomes are exclusive to males. This means that a man can determine his ethnicity mix directly through his male ancestral line. Moreover, y-chromosomes pass down from father to son, like the surname. Therefore, there are speculations and attempts to find any DNA matches between families with the same surname.

·       Single Nucleotide Polymorphism (SNP)

SNPs tests include evaluating a huge proportion of genetic variations in the entire genome structure of an individual. Experts compare your test results with the test results of those who have already undertaken the SNP testing. This helps individuals reveal their ethnic background mix by finding DNA matches in other people’s test results. It is better than other ethnicity and ancestry lineage determining tests because it provides an overall estimate of an individual’s ethnic background and mixes.

DNA Testing For Ethnicity

·       Mitochondrial

Mitochondria are the powerhouse of a cell that produces proteins. While there is DNA in the nucleus of every cell, mitochondria carry their own form of DNA strands which provide them instructions. You should know that mitochondria DNA isn’t exclusive to females. However, they do pass down solely from a female ancestor, which means that they are a suitable way of finding your ethnic background through your female ancestral lines.

DNA Testing For Ethnicity: Conclusion

Do you want to have DNA testing performed for legal or personal reasons? Do not choose a DNA testing services provider without adequate consideration. Pay attention to whether the company uses standard procedures, equipment, and lab setting to perform DNA testing. More so, you should learn whether the DNA testing services provider is AABB-accredited or not.

With AB DNA Testing, you can have peace of mind, as we are AABB-accredited, use modern equipment, have standard procedures, and employ friendly and professional staff.

What is DNA?

DNA refers to the deoxyribonucleic acid molecule, which contains vital instructions and data for organisms to develop. Nearly all living organisms have some type of DNA that guides the growth of their body through development and reproduction. DNA contains essential living information and is present inside nearly every cell, which passes down from generation to generation.

What is DNA?

From a medical point of view, DNA testing allows solving multiple problems relating to paternity, biological identifications, lineage, and ancestry. From a scientific point of view, the studies on DNA have developed comprehensible concepts that enhance the learning of human biology. So, let’s discuss in detail what DNA is.

What is DNA?

It is a molecule (biomolecule), deoxyribonucleic, that contains genetic information specific to every organism. Whether it’s plants, bacteria, or humans, all comprise essential DNA information which is the foundation of our growth. Because DNA is hereditary, it passes down to generations, which enables the identification and detection of ancestry and lineage. In simple words, our genes contain the genetic material that defines who we are. All our physical traits, including height, shape, size, color, and more, is present in our genes as a form of hereditary information (codes).

·       Genes

A single gene refers to an individual length of DNA that is responsible for coding a particular protein. For example, one gene is responsible for the hormones that regulate blood sugar levels in your body. Thus, it codes the protein “insulin.” In particular, a human has around 30,000 genes in total. What’s more interesting is that our genes account for a mere 3% of our entire DNA, while the remaining DNA isn’t easily understandable yet. Experts believe that DNA has key functions, which include translation and transcription regulation.

What is the Structure of DNA?

DNA consists of nucleotides which are biomolecules. Each of these contains a sugar group, nitrogen base, and phosphate group. The four complex types of nitrogen bases that make up the DNA include thymine (T), guanine (G), cytosine (C), and adenine (A).

Normally, the nucleotides can join together to form two combined, long strands that create a spiral structure. Experts refer to it as a “double helix.” In the ladder-like double helix structure, experts suggest that we assume the sides to be sugar molecules and phosphate. Also, we regard the base pairs as rungs. In general, the bases of a single strand pair with the bases of another strand. Despite the size of a single DNA strand, an average human can contain over 3 million base pairs. In addition, nearly 99 percent of such DNA bases are identical in every human.

What are the Primary Functions of DNA?

Gene Expression

Every single cell in our body has the same type and form of DNA. However, each DNA still performs different functions for each cell and makes every organ behave distinctively. It is due to the gene expression, which refers to DNA as “traffic regulators” that actively instruct the cells to produce specific proteins.

Encoding information

Since we were talking about base pairs and genes, you should remember that four major bases of DNA organize themselves into genes, i.e., A, G, T, and C. The labels of the nitrogen base on your DNA are the language through which we comprehend and study genes. The genes’ codes base decides which proteins and amino acids to produce. Bear in mind that these are the vital functional and structural units of a cell. Overall, this process of forming and coding proteins is “transcription.”

What is DNA for testing


It is a fact that both DNA strands house identical genetic information. However, DNA replication is highly necessary for our bodies to develop/function accordingly and pass the information down to the follow-up generation. Without this process through base pair sequences, it becomes impossible to produce the same type, form, and specification of DNA molecules that pass down as hereditary information.

Why is DNA Testing Important?

Firstly, DNA testing is essential because there are instances in some people’s life where they want to inquire and learn more about their lineage (heritage). DNA testing can often reveal critical biological data such as gene information, which may hint towards a higher risk of contracting certain diseases. Additionally, DNA testing helps in diagnosing genetic disorders. This occurs when a person contains genetically mutated DNA. Learning whether you are a carrier of any genetic mutation can predict the chances of your children having the same conditions in the future as well. Moreover, genetic testing helps identify if a person is at risk of experiencing a genetic disorder.

For instance, one sort of gene mutation related to the BRCA2 and BRCA1 genes significantly raises the chances of experiencing ovarian or breast cancers. Therefore, DNA testing can reveal valuable data and point out if a person is susceptible to likely diseases for all the gene mutations they carry.

The United States Citizenship & Immigration Services: History and Functions

The United States Citizenship and Immigration Services is the federal government agency that processes legal immigration applications. This agency comes under the regulation of the U.S. Department of Homeland Security. This organization ensures the security and safety of the homeland against terrorism and other threats. The USCIS performs various missions for DHS and administers the national immigration system to make it efficient.

History of United States Citizenship & Immigration Services

USCIS was established in 2002 under the Homeland Security Act. Since March 1, 2003, the agency has been performing responsibilities for the federal government, including immigration services. There are more than 200 USCIS offices in the entire world. Furthermore, it contains nine program offices, four directorates, and more than 19,000 employees. The main role of this agency is to process applications and petitions.

United States Citizenship & Immigration Services

Responsibilities of USCIS

The USCIS performs three major activities, including adjudication of naturalization petitions, adjudication of immigration petitions, and consideration of asylum and refugee. Other than that, a number of tasks fall under the USCIS’ authority. These tasks and services include change-of-status petitions, employment authorizations, and other immigration-related services. The agency directly manages all the payments and costs, including their processing functioning expense. However, there are fee charges that they manage indirectly, such as administrative overhead. Below, we will mention some activities that this department performs. Besides humanitarian functions, all the other activities include an associated fee.

1.     Immigration Adjudication

Every year, USCIS process more than six million petitions. Among those, five million petitions are temporary nonimmigrant status, and one million are permanent. USCIS includes a panel of judges that determines the eligibility of lawful permanent residents, immediate relatives, and other relatives of U.S. citizens. Furthermore, the agency also evaluates the immigration criteria for the family members of the employees working in U.S. businesses. Also, they make sure that these employees and family members fulfill all the requirements for immigration. The panel will also determine the eligibility of temporary visas for foreign nationals.

2.     Work Authorization

USCIS panel of judges also authorize aliens (foreign nationals) to visit the country. They will ensure that the aliens fulfill the agency requirements before traveling to the country. They will process the applications and approve them if applicants meet all requirements.

3.     Employment Verification

E-Verify or Electronic Employment Eligibility Verification program also comes under the supervision of USCIS. This program compares information from the employer with the data that employees enter in Form I-9. This tool confirms employment eligibility and records this information to the Social Security Administration and the U.S. Department of Homeland Security. In simple words, this program ensures that employees have a lawful status for working in the United States.

4.     Fraud Detection and National Security

USCIS confirms the eligibility of the immigrants applying for a different status. They have the authority to approve and reject the application. If you fail to meet legal requirements, USCIS will reject the immigration application. USCIS also works with the law enforcement entities using two major divisions that are National Security at the agency and Office of Fraud Detection. These agencies work together and handle the individuals with petitions and applications that cause a threat to national security. Furthermore, they will determine the identity of systemic fraud.

5.     Civic Integration

USCIS also conducts training sessions and instructs new citizens about the responsibilities and rights to live in the US as immigrants. They will offer informational sources and tools so immigrants can adjust to the new country. For instance, they manage the Immigrant Integration Grants Program and Citizenship Resource Center’s website.

6.     DNA Testing for Immigration

USCIS also regulates the immigration application to identify the relationship between sponsors and applicants. They will check for critical documents such as birth certificates and other information. The purpose of these documents is to identify the relationship. However, when there is insufficient information about the relationship, the agency will ask for DNA testing. The DNA testing is performed in a listed laboratory. The authority will not accept the DNA test from any lab other than the ones accredited with AABB. AB DNA is a listed DNA testing center that performs tests with accuracy and professionalism.

Immigrating Family to New York: Do you Need to Get a DNA Test?

DNA testing is quite common in the United States. People undergo DNA testing to find the answers to family-related questions. Some people get the test for documentation and immigration. Meanwhile, others are curious about learning who they’re related to. DNA testing becomes necessary when the court needs proof of relation, or when you apply for family immigration. This is a type of medical test that determines the difference in proteins, chromosomes, and genes. Read on to learn more about DNA testing for immigration.

Immigrating Family to New York DNA Test

DNA Testing for Immigration

DNA Testing for immigration is an accurate test to verify the family relationship. You require DNA testing if there is no medical record or credible document as proof of the relationship. These documents and proofs include photographs, birth certificates, and school records. You can obtain DNA tests for:

  • USA citizenship petition
  • Immigrant visa
  • Consular Reports of Birth Abroad
  • Applications for U.S. passports

Guidelines of DNA Testing for Immigration to New York

When you want to claim a relationship to immigrate to New York, but you do not have document proof, the USCIS will ask you to take a DNA test. Furthermore, you must process the test results with AABB-Accredited Laboratory. AB DNA Testing NYC is among a few of the AABB-accredited facilities. This means that USCIS and the U.S. Department of State consider our DNA test credible for U.S. Immigration. Our qualified team has extensive experience in conducting successful DNA tests with accurate results.

According to the guidelines by the immigration office, your test result should show at least a 95% probability that you are related to the applicant. In this case, the third-party testing lab will collect, identify, and process the DNA tests. The test would be conducted under a strict “chain of custody”. The testing laboratory uses high-precision DNA testing technology.

Many laboratories collect samples using a Q-tip-type swab. They insert the buccal swab in your mouth and collect samples from the cheek area. Laboratories also use blood samples to collect the specimen. But, buccal swabs are popular as they are a non-invasive and painless method of sample collection. Both these tests have a similar accuracy rate.

Reasons for DNA Testing for Family Immigration to New York

If the immigration departments have doubts about your birth or you can’t provide sufficient proof of relation, they will ask you to share DNA test results. Make sure to check the complete requirements for DNA testing by the US government. When you claim that you are closely related to an immigration applicant, the New York immigration office will require proof. A DNA test is the most accurate procedure to identify a relationship between the beneficiary and petitioner. Also, it indicates how closely related they are.

Detention of False Claim and Fraud

When you apply for immigration to New York City, it’s imperative that you provide correct paperwork, details, and information. You cannot get away with any attempt of fraud or false claim. DNA testing is necessary when you do not have a close relationship with the beneficiary or petitioner. In this case, you need to go through a DNA test and justify your relationship. There isn’t any chance of false claims as a reputable testing organization will conduct the test and share the results with the NYC immigration office.

The tests by AABB accredited labs are error-free and highly accurate. If you fail to ensure complete transparency during the immigration process, you risk facing serious consequences.

DNA Test for Petitioner and Beneficiary

The requirement of DNA Testing depends on the officials. Sometimes, they ask to take the test even if the documents are complete. As a beneficiary or petitioner, you should stay ready to take the test whenever the authorities ask. The common tests include parental testing, half-brother or sister testing, siblings, and avuncular relations. Uncle, aunt, and grandparents also qualify for the test. Upon visiting the DNA testing center, you need to submit the buccal sample. Most testing facilities require the buccal sample to conduct the test.

Immigrating Family to New York need DNA test

Because these relations share a large amount of the same DNA, there are plenty of similarities in the structure. These similarities work as proof of relationship with the petitioner or beneficiary. In DNA testing, lab workers will analyze your DNA profiles and consider them with your potential relative. As genetic techniques advance with time, more accurate and rapid testing procedures are available. You will get the results in one or two weeks.

What is Deoxyribonucleic Acid DNA?

Deoxyribonucleic acid or DNA is a molecule inside our body. It is inside our cells, or more precisely, inside the nucleus of the cell. DNA serves a storage purpose inside our bodies, storing our genetic coding or genetic information inside each cell.

What is Deoxyribonucleic Acid DNA?

It stores the information and genetic instructions responsible for how our body functions, internally and externally. It’s a billion-letter assembly code that provides instructions for everything that you are, from physical features to emotional tendencies.

What is Deoxyribonucleic Acid DNA: The Structure of DNA

To identify DNA under a microscope or even a picture, you should know some of its key structural features. When you browse through the array of different DNA pictures, you will find different types of illustrations that represent the DNA molecule.

Each will be different in quality and color; however, they all will depict the same pattern of the structure. In medical terminology, the structure is a double helix, in which two strands of the DNA are intertwining and forming a twisting ladder.

For a simpler representation, you can unwind the double-stranded structure and look at the two strands separately. Each strand consists of individual units or Nucleotides. Each Nucleotide consists of a nitrogenous base, phosphate, and sugar.

All the nucleotides in each strand join because of the bond between the two nitrogenous bases on each strand. Every nucleotide has one of four different nitrogenous bases in the body that are compatible with their suited pairs.

Holding these pairs of A, G, T, and C are hydrogen bonds in between. The structure of the DNA compound was a breakthrough research paper of the 1950s by James Watson and Francis Crick. In this paper, they also found a way in which DNA replicates.

You may wonder why cells make copies of the DNA –well, this is because cells are always multiplying. Also, if one nucleotide has an Adenine nitrogenous base, then it can only pair with Thymine. Likewise, guanine only bonds with cytosine.

These nitrogenous bases or base pairs are the order of the nucleobases that allows them to create you. There are more than three billion pairs of these bonds in each cell. This is astounding because there are trillions of cells inside your body.

What is a Gene?

When you take one section of the DNA, you find different nucleotides connecting with their ideal opposites, representing a gene. A Gene is a small section of DNA that holds instructions that your body needs to build proteins.

For this reason, people will often compare DNA to a blueprint. This means that it is instructions that you need to build something. Genes instruct our cells on how to build necessary proteins in our body that are responsible for all the chemical reactions keeping us alive.


Considering the amount of multiplication and the large numbers of DNA molecules inside your body, there is always a chance of mistakes in the genetic coding. Genetic coding refers to the order of nitrogenous bases and how they depict our characteristics and vulnerabilities.

Hollywood tries to display mutation as a good thing that gives you powers and extra strength. However, it is the complete opposite. In reality, a mutation is a change in our DNA sequence. The good news is that our body has enzymes that often correct mutations.

The enzyme will cut out and remove the mutation or wrong sequencing of the nitrogenous base so that the right nitrogenous base can fill in its place. Thus, it prevents the mutation from happening.

Genetic Testing

Genetic testing is another form of medical test that allows you to observe your chromosomes, genes, and DNA. The results of this test can verify and find out plenty of things, and you can apply for it for numerous purposes.

What is Deoxyribonucleic Acid? DNA testing

The result of the genetic test can confirm whether you are susceptible to a medical disease or condition in the future, allowing you to prepare for it beforehand and take the right precautions. Additionally, people often use genetic testing to confirm the paternal and maternal relationship of a child.


Genetic testing is highly accurate, which is why many firms and governments rely on genetic testing to confirm or resolve a particular case. People looking to migrate to their parent’s country on an invitation have to provide a genetic test to prove their relationship.

Similarly, a person filing a report over child custody also has to provide the court with a DNA test that proves their relationship with the child.

USCIS DNA Testing Procedures

The United States Citizenship and Immigration Services (USCIS) has specific rules about DNA  testing procedures for VISA applications. However, this test isn’t mandatory and is completely voluntary. By getting this test, it doesn’t guarantee your visa, but it may help in other areas. More specifically, if there is no credible proof of a relationship with someone you might be living with or for someone who is sponsoring you.

The USCIS DNA testing procedures involve the standard DNA test taken for different purposes. This DNA test verifies a biological relationship, especially when there is no credible evidence. Some of the most common types of DNA testings include maternity, paternity, as well as full, and half-siblings. Your visa consular might advise for a DNA test. In that case, you should learn more about the USCIS DNA testing procedures.

USCIS DNA Testing Procedures

Why Will You Need DNA Immigration Testing?

You may have to go through the USCIS DNA Test if there is no credible proof of an existing relationship. These documents usually come in the form of birth certificates, school records, and photographs. By getting a DNA test, you may be easily able to achieve certain documents and applications. For example, the application for U.D Passports and Immigration Visa is easy to get once you have a DNA test. You can also have access to U.S Citizenship Petitions and Consular Reports of Birth Abroad (CRBA).

These documents do not guarantee you a visa, but it’s just to confirm certain undocumented proof. DNA testing for immigration isn’t mandatory unless the visa counselor advises you to get it.

USCIS DNA Testing Process

Mentioned below is the step-by-step explanation for the USCIS DNA testing process. This explanation will give you a slight idea of what to expect and what you will go through if you plan to get one.

1.     Getting in Touch with an Accredited Laboratory

If your Visa officer advises you to get a DNA test, you will first have to choose an authentic laboratory. Here you can give your DNA sample, which they can use to their advantage. Make sure that the American Association of Blood Banks accredited the Laboratory you choose.  Beware of labs that do not associate with the AABB or who lie about being affiliated. The visa officer will only accept DNA reels from AABB-accredited labs.

2.     Sample Collection

After setting an appointment at a credible laboratory, you will have to submit your DNA sample through a buccal swab. Once the technician receives your swab, the AABB collection clinic will give a test kit to the main lab testing site. You will not receive the DNA test kit yourself as the test kit will go directly to the U.S Embassy.

3.     Embassy Connects with the Applicant

Once the embassy has their hands on your DNA kit, they will get in touch with the applicant that is you. You will then need to provide them with a DNA sample and make an appointment to visit the consulate or embassy.

USCIS DNA Testing Procedures for Visa

4.     Payment Procedure

You have to make sure that your family member makes arrangements for payment before going in for the appointment. Only with the payment will the embassy assign a panel where they will take the DNA sample. They will receive a receipt that they have to bring to their appointment, which will take place at the U.S. Consulate. Your family member will not be able to go through the DNA collection appointment without the receipt. Therefore, they must make sure they don’t forget to bring it along to the appointment.

5.     The Collection Appointment

Once the AABB laboratory successfully analyzes your DNA, they will send the results directly to the U.S. Embassy. Once they receive it, the embassy will get in touch with you to continue your visa application process. You cannot showcase results on your own, as the U.S. Embassy and consulate only accept results directly from the AABB labs. You can achieve copies by directly contacting the AABB lab.

The USCIS DNA Testing process isn’t that complex. You just have to follow all the rules and have an accredited AABB lab in the United States of America take your test.

USCIS DNA Testing Procedures: Final Words

The USCIS DNA testing is a pretty big deal, especially when you’re going through it for visa or other important immigration purposes. Hence you must make sure you get every detail right.
