Immigration DNA Test
“Will I get a clear, reliable answer?” “How soon will I know?” “Can I talk to someone who will not judge me?”
Immigration DNA testing proves a biological relationship for a visa, green card, or family petition when documents are not enough. TestMark DNA coordinates AABB-accredited, chain-of-custody collection between the petitioner in the U.S. and the beneficiary abroad, then sends results directly to the requesting agency. Because every case is tied to a USCIS officer or embassy, the first step is a phone call.

When Is Immigration DNA Testing Needed?
A USCIS officer or U.S. embassy may request DNA testing when documentary evidence of a family relationship is missing, incomplete, or in question. These are the most common situations where it is used.
A U.S. Embassy Request
When a consular officer reviewing a visa interview abroad asks for DNA confirmation, we coordinate supervised collection at the embassy or consulate handling your case.
Insufficient Documents
When the paperwork submitted with a petition does not adequately establish the claimed relationship, DNA testing provides objective, scientific proof to move the case forward.
Family Reunification
Confirm sibling, grandparent, or other biological relationships so family members can be reunited under the petition with reliable evidence of the connection.

Frequently Asked Questions
Who orders an immigration DNA test?
Testing is initiated at the request of the USCIS officer or U.S. embassy handling the petition, not by the family on its own. Once you receive that request, call us with the letter and we will coordinate collection for everyone involved. The petitioner in the U.S. is typically responsible for the cost.
Does USCIS require an AABB-accredited laboratory?
Yes. USCIS and U.S. embassies only accept immigration DNA results from an AABB-accredited laboratory that uses a strict chain of custody. Results from a non-accredited lab or a home test are not accepted for immigration purposes.
How does testing work when one person is overseas?
The petitioner in the United States is swabbed at a nearby certified collection site, and we ship a sealed collection kit to the U.S. embassy or consulate in the beneficiary’s country. The beneficiary is collected there under supervised, chain-of-custody conditions, and the samples are returned to the U.S. laboratory for analysis.
What kind of sample is collected?
The standard sample is a painless cheek swab, also called a buccal swab, taken from inside the cheek. It is quick, non-invasive, and works for participants of any age, including infants. A trained collector performs it under chain of custody at every location.
How long does immigration DNA testing take?
Laboratory analysis is typically complete within 3 to 5 business days after all samples reach the lab. The overall timeline also depends on how quickly the embassy or consulate can schedule the overseas collection, which we work to arrange as fast as possible.
How are the results delivered?
The official report is sent directly to the requesting USCIS office, embassy, or consulate so it goes on the record for your case. The petitioner also receives a copy. Results are never released to unauthorized parties.
