Ask the Consul
Why did the consular officer request a DNA test?
For certain categories of residency visas, the consular officer may request a DNA test to prove the required biological relationship exists. DNA is the most reliable way to determine that the necessary biological relationship exists in order for an applicant to qualify for an immigrant visa. Unfortunately, these tests are sometimes necessary because of the high levels of relationship fraud that exist in the Dominican Republic and other countries. A biological relationship is a relationship established by blood line. U.S. law does not recognize informal/"crianza" relationships because they are not blood relationships.
If the consul requests a DNA test, he or she will provide you with a list of specific instructions and approved laboratories. The applicant must make an appointment with the panel physician ("Consultorios de Visas") to give his/her sample. If the other person to give sample is in the U.S. he/she can give the sample to an accredited laboratory there. The process can take about two months or more to receive the results. The laboratory will send the results directly to the IV Unit and we will then contact the applicant with another appointment with instructions on the next steps.
