What this document is
The LTR Visa and Digital Work Permit Update Form is a form of the LTR Visa Unit of Thailand’s Board of Investment (BOI) for Long-Term Resident (LTR) visa holders. It reports changes to the details recorded in the LTR visa and the Digital Work Permit.
The form has two options and only one may be selected: Part B — change of position, job description, company name or personal name; Part C — passport number update (the previous and new passports are attached).
Who fills it in and when
- an LTR visa holder whose position, duties, employer company name or personal name has changed;
- an LTR visa holder who has received a new passport.
According to the FAQ on the BOI website, a request to change company details for the Digital Work Permit is sent to ltr@boi.go.th; the officer issues a certification letter, which is then used to pay the 400 baht fee at the Department of Employment (DOE). For LTR “H” holders changing employer, the BOI asks them to email ltr@boi.go.th at least one month before the previous contract ends; the new company must meet the LTR criteria. Check the procedure for your case with the LTR Visa Unit.
What the form asks for
- Part A: first, middle and last name in Latin letters as in the passport, phone, email, current LTR visa category (W, P, H or O), work permit expiry date (dd-mm-yyyy);
- choice of section: Part B or Part C;
- Part B: previous and new position / job description / company name / personal name and the reason (if the position changes, the job description must be given);
- Part C: number, place of issue, issue and expiry dates of the previous and the new passport, and the reason;
- handwritten signature, name under the signature and date.
What to attach
- the signed form;
- for Part C — the previous and new passports (as the form itself states);
- for Part B — documents supporting the change (for example, an employer letter); check the list with the LTR Visa Unit.
The exact documents and how to submit them depend on your category and the type of change — check ltr.boi.go.th or write to ltr@boi.go.th.
