AABB-accredited DNA testing accepted by USCIS, U.S. embassies, and immigration authorities worldwide.
A Citizenship (Immigration) DNA Test is used to prove a biological relationship for U.S. immigration and citizenship purposes. Our testing is performed by an AABB-accredited laboratory, which is required by USCIS and U.S. embassies. We coordinate directly with the requesting embassy or consulate to arrange overseas sample collection when one party is abroad.
This test is for families applying for visas, green cards, or citizenship where USCIS or a U.S. embassy has requested proof of a biological relationship — including parent-child, sibling, or grandparent relationships.
Once USCIS or the embassy requests DNA testing, our team helps you initiate the process. The U.S.-based participant visits us for collection, and we coordinate with the embassy to collect the overseas participant's sample. Results are sent directly to the requesting government agency. The full process typically takes 3–7 business days after both samples arrive at the lab.
99.99%+ probability of relationship when a biological relationship exists, and 0% probability (exclusion) when it does not.
Establish legal fatherhood with a court-admissible, chain-of-custody paternity test yielding 99.99%+ probability of paternity.
Get the same 99.99%+ accuracy for personal knowledge — without the legal chain-of-custody requirements.
Establish biological relationships through grandparents when a parent is unavailable or deceased.
