Many people call it the "certificate of single status" (công hàm độc thân). It is a file legalized by the Consulate General of Vietnam that proves you are single, used to register a marriage in Vietnam.

1. Documents issued by the Consulate General

Placed at the front of the file:

  1. A letter of introduction to the competent authority in Vietnam.
  2. A Certificate of Marital Status, issued to applicants who still hold Vietnamese citizenship. It is valid for 6 months from the date of issue.
  3. Certified translations of the U.S. documents in the file.

2. Forms you complete and sign before a notary

  1. Affidavit of Single Status.
  2. Application for Marriage Registration, with photos of both partners.
  3. Biographic information sheet: work history, prior marital status and family background (parents, siblings).
  4. Statement of Non-Impediment to Marriage.
  5. One-and-the-same-person affidavit, used when your name differs between U.S. and Vietnamese documents.

3. Documents you send

  1. No Record of Marriage certificate from the County Clerk where you live.
  2. Copies of your Vietnamese passport, green card or U.S. passport.
  3. A copy of your partner’s Vietnamese ID card.
  4. Previously divorced: the divorce decree. Widowed: the spouse’s death certificate.

4. Steps

  1. Sign the forms before KPN’s notary public.
  2. Authentication by the Secretary of State.
  3. Legalization at the Consulate General of Vietnam.
  4. Send the file to Vietnam and file it with the commune-level People’s Committee where your partner resides.
