Thai-English Translation for Embassies and Government Offices
Certified Thai-English translation prepared in Bangkok for visa applications, embassy files, and official documents. We can assist with MFA requirements, review each job carefully, and format documents for acceptance.
Why Thai Translations Get Rejected at Embassies
Thai translation for official use has to match the wording, format, names, dates, and seals expected by embassies and Thai offices. Small mistakes can delay a visa file or mean the document has to be translated again.
Embassy Rejection Risk
One wrong name, date, or legal term can mean a rejected visa application and a fresh submission. our document services require specific formatting and credentials that generic translators often miss.
Qualification Uncertainty
It is not always easy to know whether a translator understands legal or technical wording. General fluency is different from accurate legal terminology or medical terminology.
Cultural Mistakes
Word-for-word translation often misses Thai formal language and official usage. Royal terms, honorifics, and business communication wording need a translator who knows the context.
Hidden Costs
Some providers quote low, then add revision, formatting, or certification charges later. A clear price for document translation should state what is included before work starts.

Translation & Review
We assign the job to a Thai-English translator familiar with the subject matter. Legal translators for contracts, medical translators for health records, and technical translators for manuals. A second linguist checks names, numbers, terminology, and readability. Every project receives a second review, which helps maintain professional quality on each document.

We provide the certification statement, translator details where required, and company seal. Minor corrections are included at no extra charge for embassy submissions.
Thai to English & English to Thai Specialists
