The Civil Documents You Need From Thailand for a U.S. Marriage Green Card
If you were born or married in Thailand, here is exactly which civil documents you need for a U.S. marriage green card, where they come from, and how to get them in English.
Quick answer
For a U.S. marriage green card, the Thai spouse generally needs the Birth Certificate, Police Certificate, and Marriage Certificate. Thailand is not an apostille country, and USCIS generally does not require legalization anyway. Non-English documents need a certified English translation, which you can self-certify.
- 3 core documents
- Birth Certificate
- Police Certificate
- Marriage Certificate
- No apostille needed
For a filing inside the U.S., USCIS accepts a certified copy plus an English translation.
- Translate it yourself
Any bilingual person can certify the English translation. No licensed translator required.
The documents you actually need
Start with these core records in order. Each one lists who issues it, what it costs, how long it takes, and exactly what USCIS wants.
Birth Certificate
What USCIS needs: USCIS requires the petitioner or beneficiary to submit a birth certificate to establish identity and, where relevant, the family relationship. Get the long-form certified copy, not an abstract.
How to get it: Request a certified copy from the district office (Amphur in a province, Khet in Bangkok) that has jurisdiction over your place of birth. The same office holds the household registration (Tabien Baan) that underlies your civil records. Many district offices can issue an official English-language version on request, which spares you a separate translation.
- Issued by
- District office (Amphur/Khet)
- Cost
- Approx 0 to 50 THB (about USD 0 to 2). Thai civil registration documents are generally issued free or for a nominal copy fee.
- Timing
- Often same day when requested in person at the issuing district office; longer if records must be retrieved from another Amphur.
Police Certificate
What USCIS needs: For consular processing (an IR1/CR1 immigrant visa handled abroad), the applicant must provide a Thai police certificate if they lived in Thailand for the required period since age 16. For adjustment of status inside the U.S., USCIS generally does not require a foreign police certificate.
How to get it: Apply at the Police Clearance Service Center, Building 24, Royal Thai Police Headquarters, Rama I Road, Bangkok, or through a Royal Thai Embassy if you are abroad. Foreign applicants typically submit a passport bio page, copies of Thai entry and exit stamps, any visa or work permit, and fingerprint cards. Fingerprints must be taken at a police station.
- Issued by
- Royal Thai Police, Criminal Records Division
- Cost
- Approx 100 THB (about USD 3) when applied for directly with the Royal Thai Police. Private expediting services charge substantially more.
- Timing
- Approximately 15 business days, and often longer for applicants applying from outside Thailand.
Marriage Certificate
What USCIS needs: If you are not yet married, the district office issues a single-status certificate, a Certificate of No Marriage or ใบรับรองโสด, confirming you are free to marry. This is the document U.S. couples commonly obtain before registering a Thai marriage.
How to get it: If your marriage was registered in Thailand, request a certified copy of the marriage registration from the district office (Amphur/Khet) where it was recorded. As with birth records, many offices can issue an English-language version on request.
- Issued by
- District office (Amphur/Khet)
- Cost
- Approx 0 to 50 THB (about USD 0 to 2), a nominal copy fee.
- Timing
- Often same day when requested in person at the registering district office.

| Topic | Details |
|---|---|
| Apostille status | Thailand is not yet operating under the Hague Apostille Convention. It acceded on 30 June 2026, and the Convention is scheduled to enter into force for Thailand on 28 February 2027 (confirm current status via HCCH). Until then, documents intended for use abroad are legalized by the Ministry of Foreign Affairs Legalization Division rather than apostilled. For a USCIS filing, neither apostille nor legalization is generally required. USCIS wants a certified copy plus an English translation. |
| How records are kept | Civil records are kept by local district offices, called Amphur in the provinces and Khet in Bangkok, each with jurisdiction over its area. The household registration book (Tabien Baan) underlies a person's civil records and links births, marriages, and residence. |
| Typical time to gather | Birth and marriage copies are frequently same day at the issuing district office. The police certificate is the bottleneck at roughly 15 business days or more. |
| Translation | Thai-language documents submitted to USCIS need a full English translation with the translator's certification of competence and accuracy. USCIS permits a competent bilingual person, including the applicant, to self-certify a translation. Easier still, ask the district office for the English-language version of the record, which removes the need for a separate translation. |

What applicants report
“Filers repeatedly report that the smoothest path is to ask the district office (Amphur) for the English-language version of the birth or marriage record on the spot, which avoids paying a translator, and to begin the police certificate first because its multi-week processing is what holds up an otherwise ready packet.”

See how it worksFrequently asked questions
Do I need to translate my Thai birth and marriage certificates for USCIS?
Yes, unless you obtain the English-language version. USCIS requires an English translation of any foreign-language document, with the translator certifying competence and accuracy. USCIS lets a competent bilingual person self-certify. The simplest route is to ask the Thai district office for the official English-language copy, which removes the translation step.
Does Thailand issue an apostille for my documents?
Not yet. Thailand acceded to the Hague Apostille Convention on 30 June 2026, with entry into force scheduled for 28 February 2027. Until then, documents for foreign use are legalized by the Ministry of Foreign Affairs Legalization Division. For a USCIS filing, you generally do not need either an apostille or legalization. A certified copy with an English translation is what USCIS asks for.
How do I get a Thai police certificate and how long does it take?
Apply through the Royal Thai Police Criminal Records Division at the Police Clearance Service Center in Bangkok, or through a Royal Thai Embassy if you are abroad. You submit a passport bio page, copies of your Thai entry and exit stamps, any visa or work permit, and fingerprint cards. The direct fee is about 100 THB and processing runs around 15 business days or longer.
I am not married yet. What proves I am free to marry?
The Thai district office (Amphur/Khet) issues a single-status certificate, a Certificate of No Marriage (ใบรับรองโสด), confirming you are not currently married. Couples planning to marry in Thailand commonly obtain this before registering the marriage.
Do I need a Thai police certificate if I am adjusting status inside the United States?
Generally no. A foreign police certificate is a consular processing requirement for immigrant visa applicants abroad. If you are already in the U.S. and adjusting status through Form I-485, USCIS does not usually require a Thai police certificate. This is general information, not legal advice.
