The Center for Medical Genetics is an AABB Accredited Relationship (DNA) Testing Facility. If you need to verify your biological relationship with a relative to obtain an immigration visa, we can provide a complete testing service.


Genetic testing is a useful tool for verifying a biological relationship in an immigrant visa application when no other form of evidence is available.

What kinds of relationships are tested?

DNA testing for immigration can determine paternity, maternity, full-siblingship, or half-siblingship. More distant relationships cannot be proven reliably using DNA testing. DNA technology is the only non-documentary method accepted for proof of a biological relationship.

When should I consider Immigration DNA Testing?

A Consular Officer may suggest DNA testing to establish the validity of the relationship(s). Such testing is entirely voluntary and all costs are borne by the applicant. Submitting to testing does not guarantee the subsequent issuance of a visa. It only verifies the biological relationship.

How is the immigration DNA test performed?

Legal DNA testing is the most accurate technology to test a biological relationship. A sample is collected by swiping a long cotton swab inside the cheek. Cheek swabs are used rather than blood samples because they are easier to collect, non-invasive, painless, and easier to ship.

How accurate is the test?

DNA testing meets the standard of 99.5 percent.

How do I get started?

As the Petitioner, contact us to make an appointment and get your cheek swabbed. We will analyze the results and submit them to the Visa office.

How does my relative (the Visa Applicant) get tested?

At the time of your testing, we will forward a DNA test kit along with a pre-addressed, pre-paid envelope to the U.S. Embassy or Consulate where your relative(s) will be tested.

They will also contact your relative (the Visa applicant) and make an appointment to come to the Embassy or Consulate to be tested. Prior to the appointment, the relative must arrange payment for the clinician who will conduct the sampling. The clinician will perform the sampling at the Embassy or Consulate. They must bring a passport, photo, and payment receipt for the clinician.
