Genetic (DNA) Testing Procedures for Visa Applicants
DNA genetic testing analyzes the genetic material in human cells and has been found to be over 99% accurate in verifying family relationships – parent/child, brother/sister, etc. DNA testing is at times suggested as a means of confirming the biological relationship between petitioners and beneficiaries. The Consular Officer may suggest DNA testing at the time of the interview or in the course of a subsequent review process. For this reason, DNA testing is suggested only when no other options appear to be available. The testing is entirely voluntary and all costs and expenses associated with it must be paid entirely by the visa applicant and/or his or her family. While we cannot require you to undergo this testing, we may not be able to continue processing your case without it. For more information on DNA parentage testing, click here.
If you decide to proceed with a DNA test, the petitioner (for immigrant visa applications) should arrange for testing with any one of the DNA laboratories accredited by the American Association of Blood Banks (AABB) through the following website (click here)
In making the choice to pursue this testing, please remember that we cannot guarantee that the tests will produce a favorable result that would allow us to issue a visa or citizenship document.
The laboratory you choose must send the testing kit to the Consulate that is processing your case. See the address list below. You must include the name and location of the office that requested the testing:
U.S. Consulate General Rio de Janeiro
Av. Presidente Wilson, 147
Rio de Janeiro RJ 20030-020
U.S. Consulate General São Paulo
R. Henri Dunant, 500
São Paulo SP 01411-001
The Consulate will receive the testing kit, and will contact the test participant(s) by phone or e-mail and schedule an appointment date for the DNA test. Appointments cannot be scheduled before a testing kit is received by the Consulate. Please contact one of the panel physicians from the list below to arrange to have the sample collected from the test participant(s) in the presence of a Consular Officer. The fee for the DNA sample collection must be paid directly to the physician.

- Once the samples are collected, the Consular Officer will assemble and secure the samples and return them by express courier to the laboratory. One of the most important aspects of the testing process is the security of the samples taken from the individuals. The chain of custody must be maintained from the moment the samples are taken by the physician until the kit arrives to the laboratory.
- Under no circumstances should petitioners use third-party vendors to select their lab, receive directly the test kits, or transport the specimens outside of the lab chain-of-custody controls. The DNA samples for the petitioner must be collected at a designated AABB testing site, lab, or clinic in the United States.
- If either the parent or child resides in the United States, the petitioner should arrange with the laboratory to have the relevant sample taken in the U.S. and follow the normal procedure for having the other sample taken in Brazil, as described above.
- You must instruct the laboratory to send the Consulate an original notification of the results, including the chain of custody. Once the Consulate has received its original copy showing the result, we will continue processing your application.
Applicants should arrive at the Consulate at the appointment time, and follow the recommendations below:
- The person to be tested must bring his/her valid passport or his/her recently issued Brazilian national ID and one copy of his/her identification document.
- The person to be tested must bring one color picture, on a white background and showing the applicant’s entire face. The photo must be 5x7cm size and must been recently taken.
- The Legal Guardians of children under age must also bring his/her Brazilian national ID, one copy of his/her Brazilian national ID and one color picture, on a white background and showing his/her entire face. The photo must be 5x7cm size and must been recently taken.
The Immigrant Visa Unit in Rio de Janeiro is able to collect paper fingerprints on behalf of the Department of Homeland Security/United States Citizenship and Immigration Services (DHS/USCIS) on cases related to adoption, immigrant visas, or naturalization processes. If you wish to schedule your interview at the U.S. Consulate in Rio de Janeiro, please send an email email@example.com. Applicants may wish to schedule an appointment for this service at the U.S. Embassy or another U.S. Consulate in Brazil. To schedule an appointment at another U.S. Consulate or at the U.S. Embassy, please visit the contact information page of the American Citizen services Unit- ACS Unit. On the day of the appointment, you must bring the two FD-258 fingerprint charts provided by USCIS.
Fingerprints requested for reasonsother than adoption, immigrant visas or naturalization processes should be addressed to the appropriate sections. Fingerprints related to non-immigrant visas (tourism, studies, business, etc) for example, should be addressed to the non-immigrant visa unit of the U.S. Embassy or U.S. Consulates.
