Thai documents, from the tabien baan to the Buddhist calendar
Thai documents live 543 years in the future: the year on a Thai certificate is Buddhist Era, so 2569 BE is 2026 — and an unconverted date can derail a visa timeline. EKO 4 converts every one: certified, word-for-word Thai-to-English translation by sworn human translators, BE dates rendered in the Western calendar, with a signed accuracy affidavit on official letterhead and our wet stamp — backed by our 100% acceptance guarantee, with express 24-hour service available.
K-1 and marriage cases dominate Thai files, and they hinge on documents with Thai particularities: the tabien baan house registration that proves residence and family, the name-change certificates that are routine in Thailand and essential for linking a birth certificate to a passport, and honorific prefixes that must be rendered so identities stay clear. Our linguists handle each daily, reading Thai script — spaces or none — in print and older clerk hands alike. Since 1991 we strive to be the most affordable, the most accurate, providing the best quality of service.

Why EKO 4 for this language
Buddhist Era dates converted
Every BE date rendered in the Western calendar, consistently across your file — the difference between a timeline that makes sense to an officer and one that raises questions.
Name changes, linked cleanly
Thai name changes are routine — and each certificate in the chain must be translated so your birth record, current ID and passport demonstrably belong to one person. We translate the chain, not just the endpoints.
