Immigrant Visa

Dear US Visa/Passport Applicant(s),

The claimed biological relationship(s) has not been established to the satisfaction of this Consulate.  Absent other credible proof of the claimed relationship, genetic testing could provide a reliable means of determining and verifying your blood relationship with the relevant person(s). 

The Department of State requires that any DNA testing for visa and citizenship purposes must be done by a lab that is accredited by the American Association of Blood Banks (AABB).  Names of AABB accredited labs can be found on the Internet at

http://www.aabb.org/Content/Accreditation/Parentage_Testing_Accreditation_Program/AABB_Accredited_Parentage_Testing_Laboratories. 

Genetic testing procedures: 

•  First, you must select a laboratory listed on the above website directly, and make the necessary arrangements (including payment) for conducting the genetic test. At your request, the laboratory will send a buccal swab kit and explicit instructions to our post.  After we receive the testing kit, we will contact you to come to the Consulate for collection of biological samples (buccal samples of the U.S. petitioner, if required, can be collected in the United States by the same U.S. lab or at the U.S. Consulate in Guangzhou);
• Biological samples will be taken by a panel physician at the Consulate in Guangzhou, RMB100 per person will be charged for the service by the panel physician;
• The samples will be returned to the designated laboratory for analysis;
• The lab must send the testing results directly to the Consulate.

Note: Please advise the laboratory to enclose a waybill from Federal Express (postage prepaid) that has an account number and the account holder’s full name on it when they send the buccal swab kit to the Consulate.  A waybill from another company will not be accepted.

If you want to make an appointment for sample collection, you can contact the Consulate at telephone number: (20) 85187600 Extension 7745.

Please have the laboratories send the test kit to the address below:
