Immigration DNA testing can feel overwhelming because it involves a government agency, an embassy or consulate, and family members who may live in different countries. Here is an overview of how it usually works.
When DNA testing is requested
U.S. immigration authorities may suggest or request DNA testing when other documents, such as birth certificates, are not enough to establish a claimed biological relationship. Testing is generally voluntary, but it may help a case move forward.
Follow the agency's instructions first
Immigration cases have specific requirements. Usually:
- The relationship testing must be performed by a laboratory accredited for this purpose (commonly AABB-accredited).
- The laboratory coordinates collection both in the United States and at the overseas embassy or consulate.
- Results are sent directly to the agency, not handed to the family.
Before booking anything, review your notice or request letter and contact us with the details. We will confirm whether and how we can help with the U.S.-side collection.
How U.S.-side collection works
For the U.S.-based participant, collection follows strict identity and chain-of-custody procedures: valid ID, photographs where required, a neutral collector, and sealed, documented samples sent to the laboratory. Precision DNA Services performs the collection at a mutually agreed-upon public meeting location that we confirm with you; the laboratory performs the testing.
Timing
Overall timing depends on the overseas appointment and the agency's processing, not just the laboratory. Plan ahead and keep copies of all correspondence.
