Immigration DNA Testing in Los Angeles

Certified Collection, Short Waits, & a Decade of Experience Behind Every Test

When a birth certificate isn’t enough to satisfy USCIS or a U.S. embassy, DNA evidence can help confirm the biological relationship at the heart of a family petition. We offer Immigration DNA Testing at Fastest Labs of LAX, serving petitioners and their families throughout Los Angeles County with certified collectors, short wait times, and direct guidance on what you’ll need to move your case forward.

Genetic testing is used to verify a stated biological relationship when other credible evidence isn’t available in connection with an immigrant visa application. The most commonly tested relationships are parent-child (paternity or maternity), full-sibling, and half-sibling. With over a decade of experience in DNA testing, our team can answer your questions and walk you through every step of the process.

Why Los Angeles County Petitioners Choose Fastest Labs of LAX

The immigration process is already lengthy. Your collection appointment shouldn’t add to the delay. We keep wait times under five minutes, operate in clean, inviting facilities, and price our services to stay accessible for individuals and families managing immigration costs.

Our certified collectors conduct every cheek swab with precision and full confidentiality. For analysis, we partner with AABB-accredited laboratories, which meet the accreditation standard immigration agencies require when evaluating DNA results. Total case timelines vary since the visa applicant’s portion depends on when the U.S. embassy or consulate abroad schedules their appointment, but the collection step on your end doesn’t have to be a bottleneck.

How the Immigration DNA Testing Process Works

The process involves two separate collection appointments: one for the petitioner here in the United States, and one for the visa applicant at a U.S. embassy or consulate abroad. Here’s how it unfolds:

Petitioner’s appointment: You schedule an appointment at Fastest Labs of LAX, provide a cheek swab sample, and we send it for laboratory analysis. Cheek swabs are used because they’re non-invasive, painless, and straightforward to ship.
Visa applicant’s appointment: Once your sample is submitted, the visa applicant schedules their collection appointment at a U.S. embassy or consulate. They’ll need to bring a valid passport, a passport-style photo, and the DNA test payment receipt. Consular officials witness the sample collection.
Results delivery: The AABB-accredited laboratory sends results directly to the embassy, consulate, or USCIS. Immigration agencies only accept results delivered this way, not from the petitioner or applicant directly. Once results are confirmed, the visa applicant can move to the next steps of the application process.

A consular officer may suggest DNA testing when other credible evidence of a biological relationship isn’t available. Participation is voluntary, and costs are generally borne by the petitioner and/or the visa applicant.

What You’ll Need to Get Started

Before your appointment, you’ll need an official written request for DNA testing from USCIS or a U.S. embassy or consulate, such as a Request for Evidence. Every adult participant must bring valid government-issued identification. If a child under 18 is being tested, a parent, guardian, or conservator must be present. Bring your official case documentation to the appointment so our collectors have everything they need to process your sample correctly.

When USCIS or a U.S. Consulate Requests DNA Evidence

DNA testing isn’t the first step in a family-based immigration case. USCIS and the Department of State typically suggest it only after primary and secondary evidence, such as birth certificates or affidavits, has proven unavailable or insufficient. It may come into play for a Form I-130 petition, a Form DS-260 immigrant visa application, or other family-based immigration benefit requests.

For petitioners in Los Angeles County, the USCIS Los Angeles Field Office handles immigration services for the area. If you’ve received a Request for Evidence or a similar written recommendation for DNA testing, that document is what you’ll bring to your collection appointment with us.

Which Relationships Immigration DNA Testing Can Verify

DNA testing can confirm parent-child, full-sibling, half-sibling, and grandparent relationships. More distant relationships generally can’t be reliably established through DNA testing alone, so confirm with your immigration attorney or case officer which relationship type applies to your petition.

One important note: submitting to DNA testing doesn’t guarantee visa issuance. It verifies the biological relationship, while your petition continues through standard immigration agency review on its own timeline.
