DNA Testing in Guangzhou, China — US Immigration & Personal Testing
Guangzhou has been the historic gateway for Chinese immigration to the United States since the 19th century, and today its U.S. Consulate General remains the only post in the country authorized to process immigrant visas — for the entire nation, regardless of which province an applicant lives in. Families here pursue DNA testing for two different reasons: some in response to an official USCIS or Consulate request tied to a family-based immigration case, and others purely for personal knowledge.

Most people don't realize there are two different tests until they start looking — and they serve very different purposes.
If you've received an official request from USCIS or the U.S. Consulate General in Guangzhou — through a Request for Evidence, a Notice of Intent to Deny, or a formal consular letter — the collection must be supervised and follow a documented chain of custody; self-collected results are never accepted for immigration purposes. If you're testing purely for personal knowledge, with no immigration case involved, a simpler self-collection option is available, with results kept completely private.

Immigration DNA Testing
Supervised, chain-of-custody collection — required when USCIS or the U.S. Embassy has requested DNA evidence for your case.

- Witnessed, documented chain of custody
- Accepted by USCIS & U.S. Embassy for immigration cases
USCIS and the U.S. Consulate General only accept DNA relationship testing results from AABB-accredited laboratories — a non-negotiable requirement. For the immigration path, the embassy or consulate itself schedules and coordinates your family member's collection appointment directly — either at the embassy or through an embassy-designated physician — once our accredited laboratory partner ships the collection kit there per the official request. We manage this coordination on your behalf; it is not an independently arranged local collection. The immigration testing process begins once you have the official request in hand, not before.

Frequently Asked Questions
For immigration cases, the U.S. Embassy or Consulate schedules and coordinates the collection appointment directly — either at the embassy itself or through an embassy-designated physician — once our lab ships the collection kit there. This is not something you or a local contact arranges independently; the embassy manages scheduling once your case is in motion.
The Consulate General in Guangzhou is the only U.S. post in China authorized to process immigrant visas — this applies nationwide, including for applicants in Beijing, Shanghai, and every other region.
No. USCIS and the U.S. Consulate do not accept self-collected results under any circumstances for immigration purposes — supervised, chain-of-custody collection is required.
The US-based petitioner's portion is typically fast, often just a few business days once samples are received. The Guangzhou-based portion depends on local scheduling and current conditions, which can vary.
The immigration path requires supervised, chain-of-custody collection tied to an active USCIS or Consulate case. The personal path is for private knowledge only, uses simpler self-collection, and isn't connected to any government process.
