Certified Translation of Thailand Documents for USCIS
Translating Thai civil documents for USCIS carries two challenges you won't meet with most other countries: nearly every official Thai record dates events in the Buddhist Era (พ.ศ.), which runs 543 years ahead of the Gregorian calendar, and Thai names have no single standard Romanization, so spellings must be reconciled with the applicant's passport. Thailand's core civil records — birth, marriage, divorce, and death — are issued by the local District Office (Amphoe), while education, police, and single-status documents come from universities, the Royal Thai Police, and the Bureau of Registration Administration. Older records are frequently handwritten in Thai-only script, occasionally with Thai numerals, and even today's bilingual Thai-English certificates still require a full certified English translation with a signed Certificate of Accuracy to satisfy 8 CFR 103.2(b)(3). Thailand acceded to the Hague Apostille Convention on 30 June 2026, but the change does not take effect until 28 February 2027 — a timing detail that matters for how these documents are authenticated.

GOOD TO KNOW
Issuing Authority & Authentication
Civil records in Thailand are issued by the สำนักทะเบียน / อำเภอ (Local Civil Registrar — District Office/Amphoe, under the Bureau of Registration Administration, Ministry of Interior; the Khet office in Bangkok) · official language(s): Thai. Thailand acceded to the Hague Apostille Convention on 30 June 2026, but it takes effect only on 28 February 2027; until then, Thai documents are authenticated by consular legalization through the Legalization Division of the Ministry of Foreign Affairs (Chaeng Watthana Rd., Bangkok). Note that for documents filed directly with a USCIS petition, USCIS generally requires only a certified English translation — not an apostille or legalization.
Every document above is translated by a native specialist, reviewed by a second linguist, and delivered with a signed Certificate of Accuracy that USCIS accepts under 8 CFR 103.2(b)(3) — or we fix it free and cover your resubmission fee.
FAQ
Frequently Asked Questions
My Thai document already has an English section — do I still need a certified translation?
Yes. USCIS requires a complete certified English translation with a signed Certificate of Accuracy under 8 CFR 103.2(b)(3). The pre-printed English on a bilingual Thai certificate is not treated as a certified translation and often omits handwritten entries, seals, and stamps that must also be rendered.
Do the Buddhist Era dates on my Thai records need to be converted?
Yes. Thai official documents use the Buddhist Era (พ.ศ.), which is 543 years ahead of the Gregorian calendar — so 2540 B.E. is 1997 C.E. A proper certified translation converts every date and can note the original B.E. figure so there is no confusion at USCIS.
How should my Thai name be spelled in the English translation?
Exactly as it appears in your passport. Thai has no single official Romanization system, so one name can be spelled several valid ways in English; we match your documents to your passport and other USCIS filings so the names line up and don't trigger an RFE.
Does USCIS need my Thai documents apostilled or legalized?
For documents you file directly with a USCIS petition, generally no — a certified English translation is what's required. Apostille or MFA legalization usually matters for consular processing at a U.S. embassy or for use by other authorities. Thailand's apostille option becomes available on 28 February 2027.
How much does a Thai birth certificate translation cost and how fast is it?
Most single-page Thai civil records run about $15–25 total at $0.05 per word, delivered in 24–48 hours, with a free 250-word sample first. Every order includes our signed Certificate of Accuracy and a USCIS Rejection Pledge — if USCIS rejects the translation for accuracy, we fix it free and cover the resubmission fee.
