Immigration DNA Testing in McKinney

When USCIS Requests Immigration DNA Testing

USCIS may ask for DNA evidence when documentary records aren’t sufficient to confirm a claimed biological relationship. This happens most often during I-130 family petitions, immigrant visa applications, Consular Reports of Birth Abroad, and passport verification cases. A Request for Evidence (RFE) or Notice of Intent to Deny is often the trigger, signaling that the agency needs biological confirmation before moving forward.

Immigration DNA testing is voluntary, and the petitioner bears the cost of testing. Results from an AABB-accredited laboratory are sent directly to USCIS or the U.S. embassy handling the case, with a copy provided to the petitioner. Keep in mind that proving a biological relationship doesn’t guarantee visa or application approval; the immigration officer retains discretion over the final decision.

Relationship Types We Test

Immigration cases involve a range of family relationships, and our testing covers them all. We provide paternity/maternity testing, full or half siblingship testing, and family-based immigration cases, including grandparent-grandchild and other extended biological relationships where testing may be requested.

We can also assist in more complex situations, such as cases where individuals were born abroad without citizenship documentation. For parties who aren’t in the U.S., we offer pre-arranged sample collection locations for individuals outside the U.S., coordinated through the applicable embassy or consulate in the beneficiary’s home country.

The Immigration DNA Testing Process at FastestLabs

Sample collection uses a non-invasive cheek swab. It’s quick, painless, and performed by our certified collectors, who maintain a strict chain of custody from collection through laboratory analysis. Every sample is packaged with tamper-evident documentation to preserve chain of custody for immigration purposes.

Home DNA kits aren’t accepted for immigration cases because they don’t establish a proper chain of custody or use a verified third-party collector. That’s why in-person collection at a qualified facility matters. Domestic results are typically available within 2-3 days. If overseas collection is involved, embassy and consulate scheduling can extend the overall timeline, but we’ll keep you informed at every step.
