Certified Thai Translation Services
Certified Thai translation for birth certificates (สูติบัตร), marriage certificates, tabien baan (house registration), and academic credentials from Thailand's district offices and universities. Our native Thai translators understand the Thai civil registration system, Buddhist Era dating, and the Royal Thai General System name transliteration used by the Ministry of Foreign Affairs.
Why Thai Documents Need Specialized Translators
Our Thai translators are native speakers with deep knowledge of Thailand's Amphoe district office document formats, the Ministry of Interior's civil registration system, and the formal Thai language register used in legal and government documents. They handle Buddhist Era to CE date conversion, Thai name romanization according to the Royal Thai General System (RTGS), and the specific administrative seals and stamps used by Thai government agencies.
Whether you need a Thai สูติบัตร translated for a USCIS filing, a ทะเบียนบ้าน (house registration) for a family-based petition, academic transcripts from Chulalongkorn or Thammasat University for credential evaluation, or Thai court documents for legal proceedings, our Thai translators deliver certified translations with accurate Buddhist Era date conversion and proper name romanization.

Why Thai Translation Requires Expertise
Thai presents unique linguistic challenges that machine translation and non-specialist translators consistently fail to handle correctly.
Buddhist Era Calendar
All Thai official documents use the Buddhist Era (พุทธศักราช/พ.ศ.) calendar — 543 years ahead of the Gregorian calendar. Year 2567 BE = 2024 CE. Translators must accurately convert and annotate these dates for U.S. authorities.
Thai Name Romanization
Thai names can be romanized multiple ways — the same Thai name might appear as "Pornpan," "Phornphan," or "Pawnpan" on different documents. Translators must match the romanization used on the client's passport for USCIS consistency.
No Spaces Between Words
Written Thai does not use spaces between words, only between clauses. Segmenting text correctly requires native fluency — machine translation frequently misparses word boundaries, producing nonsensical output.
Formal Register & Royal Thai
Thai legal and official documents use a highly formal register with Pali-Sanskrit loanwords (ราชาศัพท์/Royal vocabulary) that differs dramatically from colloquial Thai. Translators must be trained in this administrative language variety.
Machine vs. Professional Translation
See why Google Translate and AI tools can't replace certified human translators for legal documents. A single mistranslated term can delay your case or invalidate your filing.
“สูติบัตรฉบับนี้ออกให้โดยนายทะเบียน อำเภอบางรัก กรุงเทพมหานคร เมื่อวันที่ ๑๕ มีนาคม พ.ศ. ๒๕๖๗”
“This birth certificate issued by registrar Bang Rak district Bangkok date 15 March 2567.”
“This birth certificate is issued by the District Registrar, Bang Rak District, Bangkok Metropolitan Administration, on March 15, 2024 (Buddhist Era 2567).”

Certified & Notarized Thai Translation for Immigration
USCIS, immigration courts, and state agencies require certified translations of all foreign-language documents. Our Thai translations meet every federal and state requirement.
Certified Translation
Every Thai translation includes a signed Certificate of Accuracy — a sworn statement by the translator attesting that the translation is complete and accurate. This is the minimum requirement for USCIS filings, court submissions, and academic credential evaluations (WES, ECE, NACES members).
Notarized Translation
A notarized translation adds a notary public’s verification that the translator’s signature is authentic. Some state courts, foreign consulates, and government agencies require notarization in addition to certification. We provide notarized Thai translations with same-day availability.
Apostille Services
For Thai documents being used internationally, an apostille certifies their authenticity under the Hague Convention. We coordinate apostille services with the Secretary of State’s office, providing a complete package: certified translation + notarization + apostille — ready for international legal use.
