DNA Immigration Testing

When the U.S. Citizenship and Immigration Services (USCIS) recommends DNA testing to establish a parent-child or family relationship, we’re here to assist. DNATCA specializes in providing DNA relationship testing services for immigration, citizenship, and passport applications. Conducting a DNA test is the most reliable, accurate way of proving a family relationship. All of our immigration DNA tests are conducted by our affiliated AABB accredited laboratory, offering the highest standards of accuracy and reliability.

Bringing Families Together

DNA Testing Center of America is committed to helping families navigate the complexities of immigration processes. We understand that establishing a biological relationship is a critical step in these procedures, and our DNA immigration testing service is designed to provide the necessary evidence to support your immigration application.

Whether it’s paternity, maternity, or other familial relationships, our tests are conducted by an accredited laboratory with extensive experience in serving government agencies, local embassies, and immigration clients. We’ve worked with U.S. embassies on consulates worldwide, handling numerous cases around the world.

Immigration DNA Testing

Our Simple, Step-by-Step Process

DNATCA simplifies the process of DNA testing for immigration purposes. Here's how we do it:
Initiate the DNA Testing Process

Contact us at +1.855.552.3244 to start the DNA immigration testing process. We ensure all tests are conducted following all guidelines set by the United States Citizenship and Immigration Services (USCIS).

Petitioner DNA Sample Collection

We’ll reach out to the petitioner to set up a DNA mouth swab sample collection appointment. With our extensive network of collection sites across the U.S., we’ll find a location that’s convenient for you.

Applicant DNA Sample Collection

We’ll send a kit to the U.S. embassy or consulate in the applicant’s country. Once the kit arrives, the embassy or consulate will contact the applicant to schedule an appointment for DNA sample collection.

Laboratory Analysis

Once the AABB-accredited laboratory receives your DNA samples, a team of expert laboratory professionals will complete your testing within 1-2 business days.

Receive Results

Immediately once the analysis is complete, your test results will be sent directly to both you and the USCIS office requesting the DNA testing.

Chain-of-Custody Specimen Collection

A specimen collection and witnessing charge of $50 will apply for each individual whose sample is collected at one of our locations in the US, and $125 for each individual whose sample is collected overseas. A $25 charge will apply if individuals in the same case are collected at different locations.
