Thai to English Certified Translation for USCIS
Yes — Translation HelpDesk delivers certified Thai-to-English translations that USCIS accepts, with a signed Certificate of Accuracy on every page.

Every file is handled by a native Thai linguist who converts Buddhist Era dates, reconciles name spellings, and reproduces the district-office layout USCIS reviewers expect — never machine output.

ABOUT THAI TRANSLATION
Why a Native Thai Specialist Matters
Thai is written in a 44-consonant abugida in which vowels wrap above, below, before, and after their consonant, four tone marks change a word's meaning entirely, and — critically — no spaces separate words. Machine tools cannot reliably tell where one Thai word ends and the next begins, so they garble names and confuse identically spelled words. Thai official records also run on the Buddhist Era calendar (พ.ศ.), 543 years ahead of the Gregorian: พ.ศ. 2540 must be rendered 1997, and one missed conversion can void a filing. Names hold a further trap — Thailand has no single romanization standard, so a passport, a สูติบัตร, and a tabien baan may spell the same person three different ways. A native Thai linguist reconciles those spellings, tells Central (standard) Thai from Isan, Northern (Kham Mueang / Lanna), and Southern (Pak Tai) wording in older or handwritten entries, and mirrors the exact amphoe (district-office) formatting officers look for.
Where Thai is spoken: Thailand (primary source of virtually all Thai-language civil documents), United States (documents held by the Thai-American community for re-filing), Laos and Cambodia (ethnic Thai and cross-border families), Malaysia and Myanmar (southern and western border communities).

FAQ
Frequently Asked Questions
Will USCIS accept your Thai-to-English translation?
Yes. Every page includes a signed Certificate of Accuracy that meets USCIS requirements under 8 CFR 103.2(b)(3), and we stand behind it with our USCIS Rejection Pledge — if an officer ever rejects the translation over accuracy or formatting, we correct it at no charge.
How do you handle Buddhist Era (พ.ศ.) dates on my Thai document?
Thai civil records use the Buddhist Era calendar, which is 543 years ahead of ours. Our linguists convert every date to the Gregorian calendar (for example พ.ศ. 2540 to 1997) and annotate it clearly so the USCIS reviewer sees an exact, unambiguous date — a common reason DIY and machine translations get bounced.
My name is spelled differently on my passport and my birth certificate. Which spelling do you use?
Because Thai has no single official romanization system, the same name is often spelled several ways across documents. We match the spelling on your passport or green card, then add a translator's note flagging any variation so USCIS understands the records refer to the same person.
How much does a Thai civil document cost and how fast is it?
Certified translation is $0.05 per word, and standard civil documents such as birth, marriage, and house-registration certificates run a flat $15-25 each. Standard turnaround is 24-48 hours.

Do you translate the tabien baan (house registration) and Kor Ror family records?
Yes. We regularly translate the ทะเบียนบ้าน (house-registration book), Kor Ror 2 family-status records, name-change certificates, and other amphoe-issued documents, reproducing the original stamps, seals, and table layout so the certified English version maps one-to-one to your Thai original.
