Immigration DNA Testing in Chattanooga

Walk-In Immigration Testing at an AABB Accredited Lab

When a visa application hinges on proving a biological relationship, the laboratory you choose matters. Fastest Labs of Chattanooga provides immigration DNA testing in Chattanooga, TN, using fully AABB accredited laboratories. This is the standard required by USCIS, U.S. embassies, and passport agencies. With more than 10 years in the DNA testing industry, certified collectors, and clean facilities built for a comfortable experience, we’re ready to help petitioners move their case forward.

Immigration DNA testing establishes biological relationships: parent, grandparent, sibling, or another relative, between a U.S. citizen and a family member applying for an immigration visa. It’s one of the most reliable ways to verify those ties when documentation alone isn’t conclusive. Our team can guide both the petitioner and the visa applicant through every step of the process, and our services make professional, accredited testing accessible.

How the Process Works

Immigration DNA testing involves two separate collection appointments: one for the petitioner in the U.S. and one for the visa applicant abroad. Following each step carefully helps keep the case on track.

Petitioner Appointment

The petitioner, the U.S. relative sponsoring the visa application, schedules an appointment at one of our accredited lab facilities in Chattanooga. A certified collector gathers a DNA sample via cheek swab, and that sample is sent to the main testing location for analysis. Wait times at our facilities are typically under five minutes.

Visa Applicant Appointment

The visa applicant is then prompted to schedule a DNA collection appointment at a U.S. embassy or consulate. Before that appointment, the applicant must pay the required fee and bring the receipt. Arriving without it can result in the appointment being rescheduled. At the appointment, the visa applicant must present their passport, a valid photo of themselves, and the DNA test payment receipt. A cheek swab sample is collected and witnessed by officials to support accuracy, then sent to our facility for analysis.

Results

Once both samples are received and analyzed, results are made available, and the visa applicant can take the next steps in the immigration application process. Every stage is handled with the precision that USCIS and embassies require.

Why AABB Accreditation Matters for Your Case

Not every DNA test qualifies for immigration purposes. USCIS, U.S. embassies, and passport agencies only accept results reported directly from a laboratory accredited by the American Association of Blood Banks (AABB) for relationship testing. Using a non-accredited lab, including a home kit, can put the case at risk of rejection.

AABB accreditation means the laboratory follows validated procedures at every stage, from initiating the case to reporting results, with a documented chain of custody throughout. Fastest Labs of Chattanooga uses fully AABB accredited and experienced laboratories for all immigration testing, so the results meet the standards immigration authorities require.

Relationships we can verify:

Parent and child (paternity or maternity)
Grandparent and grandchild
Siblings
Other family relationships as needed for a visa application

Immigration DNA testing is voluntary. If an applicant chooses to pursue testing, they’re responsible for the associated costs.

What to Bring & What to Expect at Your Appointment

Arriving prepared helps the collection go smoothly for everyone involved.

For Petitioners Collecting in Chattanooga
Each adult participant must bring a valid government-issued photo ID. For participants under 18, a parent, guardian, or conservator must be present to sign on their behalf.

For the Visa Applicant at the U.S. Embassy or Consulate
The visa applicant must bring their passport, a valid photo of themselves, and the DNA test payment receipt. Missing the receipt means the appointment can be rescheduled, so confirming those documents ahead of time is important.

The Collection Itself
Both participants are sampled via cheek swab. It’s a non-invasive, painless process that takes only moments. The visa applicant’s sample is collected under observation by embassy or consulate officials to satisfy chain-of-custody requirements.

After Collection
Once the laboratory receives both samples, analysis begins. Results are reported to the appropriate immigration authority and handled with strict confidentiality, shared only with authorized parties. A home kit can’t substitute for this process. Immigration DNA testing requires certified collection under chain-of-custody procedures for results to be accepted by USCIS or a U.S. embassy.
