Changing employer or position on a work permit — what should you know about occupations reserved for Thai nationals?

The subject of this page is “Changing employer or position on a work permit”, so it deals with the case-specific points first and the shared rules afterwards. Before starting, verify the source document is still within any validity window the recipient applies, then count the number of certified sets needed before work starts, because extra sets restart the certification steps, then confirm with the receiving body whether it wants an original, a certified copy or a certified translation. If multiple certified sets are needed, order them all in the first round to avoid re-queuing. For documents going abroad, include international shipping time in the plan. The terms that frame this page are Changing · employer · position · work. The common failure in this group of cases is a translation that does not match the certification type required. A key variable is the filing channel (in person, agent or online), which sets the copy format to prepare. Record the reference number of each certification layer; it is the fastest way to trace status. Note who signed each certification and on what date for later reference. Once the set is complete, check it line by line against the destination's own checklist before filing. Some occupations are reserved for Thai nationals under royal decrees and announcements issued under the Royal Decree; the prohibited and conditional lists are revised from time to time, so the list in force on the filing date must be checked. Work by foreign nationals in Thailand is governed by the Royal Decree on Managing the Work of Aliens B.E. 2560 (2017) as amended by Decree No. 2 B.E. 2561 (2018); work permits are issued by the Department of Employment, Ministry of Labour. ILC handles the document side only — certified translation, notarial signature certification and legalisation runs at the Department of Consular Affairs or an embassy. ILC is not the deciding authority and cannot guarantee an approval. Cost and lead time depend on page count, language pair and the certification steps the receiving authority requires, so every file is quoted before work starts.
