DNA testing has become one of the most reliable ways to prove biological relationships for U.S. immigration and visa applications.
If traditional documents (like birth certificates or family records) are unavailable or questioned, the USCIS (U.S. Citizenship and Immigration Services) may request a DNA relationship test to verify family ties.

In this article, DNA Centers USA explains the complete process — from requirements to costs and how to get your test approved in 2025.
Why USCIS Requires DNA Testing
The U.S. Department of State (DOS) and USCIS use DNA tests as a supplemental form of evidence when:
- There are missing or unreliable birth records
- The relationship between petitioner and beneficiary needs scientific confirmation
- The case involves family reunification, visa sponsorship, or green card applications
A DNA test provides 99.99% certainty of a biological connection and is recognized by U.S. embassies and immigration authorities worldwide.

What Is an Immigration DNA Test
An Immigration DNA Test verifies a biological relationship between:
- Parent and child
- Siblings
- Grandparents and grandchildren
- Other claimed family members
Unlike home kits, these tests must be done by AABB-accredited laboratories to ensure authenticity and traceability — otherwise, USCIS will not accept the results.
📍 DNA Centers USA partners exclusively with AABB-certified labs, ensuring that all results meet USCIS and embassy standards.
Documents Required
To start the process, you’ll need:
- Photo ID (passport, driver’s license, or green card)
- USCIS or embassy case number
- Signed consent form for each participant
- Petitioner and beneficiary contact information
Each sample is collected under chain-of-custody to ensure legal validity.
Step-by-Step Immigration DNA Test Process (2025)
Here’s exactly how it works:
1. USCIS or Embassy Recommends DNA Testing
If you submitted insufficient evidence, the immigration office sends a Request for Evidence (RFE) recommending DNA testing.
2. Choose an AABB-Accredited Lab
Contact an approved provider like DNA Centers USA, which manages testing nationwide and coordinates with U.S. embassies abroad.
3. Sample Collection in the U.S.
For petitioners in the U.S., DNA samples are collected at a certified collection center.
Each participant must show a valid ID and case number.
4. Sample Collection Abroad
If the beneficiary lives outside the U.S., DNA Centers USA sends a test kit to the U.S. Embassy or Consulate in their country.
A trained official collects the sample and ships it back securely to the accredited U.S. lab.
5. Laboratory Analysis
The DNA is analyzed for 16–21 genetic markers using advanced PCR methods.
Results are cross-checked for precision and certified by the AABB laboratory.
6. Result Submission
Once completed, the results are:
- Sent directly from the lab to the USCIS or Embassy (to prevent tampering)
- A copy is also provided to the petitioner for personal records
