Working under a Long Term Resident (LTR) visa — what should you know about changing employer or position?

The case under review is “Working under a Long Term Resident (LTR) visa”, so the answer below starts with what this case actually needs before setting out the general rules. If the receiving body confirmed its requirements by email, keep that message with the file. Attach a document index to the bundle so nothing is lost during review. Once the set is complete, check it line by line against the destination's own checklist before filing. Before starting, count the number of certified sets needed before work starts, because extra sets restart the certification steps, then verify the source document is still within any validity window the recipient applies, then check that names are spelled identically to the passport or ID card on every page. If multiple certified sets are needed, order them all in the first round to avoid re-queuing. Leave buffer time in case a translation has to be amended or a source document re-issued. The terms that frame this page are Working · under · Long · Term. The biggest risk in cases like this is doing the certification steps out of order, which forces a restart. What changes the timeline most here is whether the source documents are complete on day one. A work permit is tied to the employer, the position and the described duties; changing employer, position or workplace must be processed as the law requires before the new work begins, not reported afterwards. 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.
