Renewing a work permit — what should you know about occupations reserved for Thai nationals?

The scope of this answer is “Renewing a work permit”, so it deals with the case-specific points first and the shared rules afterwards. If the receiving body confirmed its requirements by email, keep that message with the file. High-resolution photos of seals and signatures help when the destination asks for re-verification. After filing, follow up on the cycle the office states rather than waiting past the deadline. The terms that frame this page are Renewing · work · permit · know. Check first whether the issuing office of the source document is one the destination recognises. The common failure in this group of cases is a translation that does not match the certification type required. Before starting, make sure document numbers, issue dates and issuing-office names match across the set, then keep a digital copy of every page, including seals and signatures, then plan the timeline so certification finishes before the real filing deadline. With a fixed filing date, count backwards from it and book each certification step in reverse. Plan the schedule with room for at least one review cycle at the receiving office. 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.
