Parentage Testing through DNA Collection

On occasion, the U.S. Consulate will request parentage testing when the primary evidence of parentage is insufficient. Most frequently, parentage is tested through DNA collection.

Please note that you are responsible for all costs. While prices will vary, most people will spend about 3,000 Hong Kong Dollars on the whole process. This is the only accepted DNA process for our needs; internet kits or tests from other sources are not acceptable. The entire process take approximately three to six weeks.

The Department of State requires that any DNA testing for visa and citizenship purposes be done by a lab that is accredited by the American Association of Blood Banks (AABB). A list of AABB accredited labs can be found on this website: AABB Accredited Relationship (DNA) Testing Facilities


Select a laboratory in the United States (please see the website above).



Request the U.S. laboratory that you have chosen to send a buccal swab kit and explicit instructions directly to the U.S. Consulate General at the following address:

Accountable Consular Officer
Consular Section
26 Garden Road
Central, Hong Kong

After we receive the testing kit from the U.S. laboratory, we will contact you to arrange an appointment to come to the U.S. Consulate General. (If one individual lives in the U.S., he/she should arrange to have the buccal sample taken by the AABB accredited lab in the U.S.)

Come to the Consulate at the appointment time for the buccal sample collection. It is a simple cheek swab and takes 10-15 minutes. The HKD $2,000 fee for this service will be collected by the laboratory technician who will take the sample. Please bring to your appointment:

  • your passport
  • one copy of your passport biographical page
  • one visa size photo (5 cm x 5 cm)
  • HKD $2,000 cash for fee payment

We will send the sample directly to the U.S. laboratory you have chosen for DNA testing.

A few weeks later, the U.S. laboratory will send the DNA test results directly to the U.S. Consulate General. We will review the results and contact you for further processing.

Please note that DNA testing does not guarantee the issuance of a visa and that all expenses must be paid in advance by the applicant and/or petitioner. For further details about the DNA testing procedures, fees, and other administrative issues, please contact the appropriate AABB accredited laboratory.
