Immigration DNA Testing in Knoxville

Documented DNA Collection for Family-Based Immigration

Immigration DNA testing can provide evidence of a biological relationship when documents submitted in a family-based immigration case aren’t sufficient. At Fastest Labs of West Knoxville, we collect DNA samples for legal scenarios involving immigration and work with facilities accredited by AABB (Association for the Advancement of Blood & Biotherapies) for testing and processing.

U.S. Citizenship and Immigration Services (USCIS) may suggest voluntary DNA testing after determining that primary or secondary documents don’t adequately establish a claimed relationship. A U.S. consulate or embassy may make a similar recommendation during consular processing. We also partner with attorneys to help clients follow testing instructions and meet court deadlines, including those associated with a Request for Evidence or Notice of Intent to Deny.

Immigration DNA Sample Collection Appointments in Knoxville

Our certified staff use a buccal swab to collect cells from inside the cheek. Their training and experience support a process centered on privacy and confidentiality. Although the collection is straightforward, careful identification and documentation are essential in an immigration case.

Chain of custody is the documented record connecting each sample to the person tested, from collection through laboratory processing. We tailor our collection services to the client’s circumstances and applicable instructions. Our testing packages are affordably priced without sacrificing accuracy or speed, though processing times depend on the case and the authorities involved.

Information that can help us understand your collection needs includes:

The immigration authority involved: Identify whether the request concerns USCIS, a U.S. consulate, or an embassy.
The people being tested: Explain which relatives are in the U.S. and whether anyone is abroad.
The written request: Provide details from any immigration notice, attorney instructions, or collection directions you received.
The applicable deadline: Share the date listed on a Request for Evidence, Notice of Intent to Deny, or other legal document.

Discuss Your Immigration DNA Collection

We can review the information you received and discuss a testing service tailored to your needs. If an attorney is assisting with your case, we can coordinate with the attorney about collection instructions and relevant deadlines.

Our contact form provides another way to share information about your request. We focus on the documented collection instructions rather than offering legal advice or predicting an immigration decision.

How USCIS & Consular Authorities Treat DNA Evidence

USCIS can’t require DNA testing by statute or regulation. The agency instead treats it as voluntary secondary evidence that may be suggested when other records don’t sufficiently establish a biological relationship. Petitioners or applicants are responsible for the associated testing costs.

A consulate or embassy may also recommend voluntary testing when the submitted evidence is insufficient. Under consular guidance, the purpose is to verify a claimed biological relationship, not to request testing intended to disprove one. A positive result doesn’t guarantee approval because immigration authorities consider the full petition or application.

Sample Collection for Relatives in the United States & Abroad

Immigration authorities generally accept DNA results only when the samples remain within the required chain of custody. Results from privately obtained tests handled by the petitioner or beneficiary generally aren’t accepted by USCIS. The testing facility must deliver completed results directly to USCIS or the applicable consulate or embassy rather than routing them through the applicant.

The documented process can differ based on where each relative is located:

Collection in the U.S.: The person being tested attends a documented buccal swab collection where identity and sample information are recorded for the chain of custody.
Collection outside the United States: The accredited laboratory sends the collection kit directly to the appropriate consulate. Collection is typically completed by an authorized panel physician, meaning a doctor approved for immigration-related examinations, or a designated medical technician.
Delivery of results: After processing, the accredited laboratory sends the results directly to the immigration authority handling the case.

For overseas testing, applicants should follow the instructions issued for their case. These instructions govern where collection occurs, who performs it, and how the laboratory submits the results.
