Interpreting at Thai immigration offices
In short
Immigration counters under the Immigration Act B.E. 2522 (1979) work in Thai. An interpreter keeps the applicant's answers consistent with the written application, which matters most in extension, TM.30 and 90-day reporting interviews where an officer asks follow-up questions about address, employer or funds.
The officer, not the interpreter, decides the case. Our role is limited to rendering the question and the answer faithfully, flagging when a term has no direct equivalent, and never adding advice at the counter. Immigration practice varies between offices, so we ask for the office name in advance and confirm what that office expects on the day.
Where the interview touches documents issued abroad, those documents normally need legalisation before they are accepted. Since 22 December 2024 the HCCH Apostille Convention is in force for Thailand, so many foreign public documents now carry an apostille instead of a double-legalisation chain — confirm the accepted form with the receiving office.
What we need from you
- Immigration office and appointment date/time
- Visa or extension category applied for
- Copy of the application form and passport bio page
- Any supporting documents the officer has already asked for
Watch out
Answers given verbally that contradict the written form are the most common cause of a same-day rejection. Reconcile the form before the appointment, not at the counter. Scope, turnaround and fees are confirmed by IVC staff by phone, LINE or email — this site does not publish prices.
