DNA Testing in Kolkata, India — US Immigration & Personal Testing

Kolkata is the capital of West Bengal and home to the U.S. Consulate General, which handles immigration matters for West Bengal, Bihar, Assam, and the rest of India's northeastern states. 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.

Two kinds of testing

Which test do you actually need?

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 Kolkata — 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.

Personal Knowledge

Informational Testing

A private, self-collected cheek swab for personal peace of mind — not connected to any immigration or government process.

  • Collect on your own time
  • Results in a few days
  • Not accepted for USCIS or embassy cases
Immigration & USCIS

Immigration DNA Testing

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

  • Photo ID verified at collection
  • Witnessed, documented chain of custody
  • Accepted by USCIS & U.S. Embassy for immigration cases
USCIS & Embassy requirement

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.

Common questions

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 Kolkata covers West Bengal, Bihar, Assam, and eight other northeastern states. Your case coordinator can confirm the specific office handling your file.

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 Kolkata-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.
