The employment contract and salary letter for a work permit file in Ayutthaya — how are they translated and certified?

This question is specifically about “The employment contract and salary letter for a work permit file in Ayutthaya”, so it deals with the case-specific points first and the shared rules afterwards. The most frequent cause of delay in this group is missing supporting documents on the first submission. The condition most often overlooked is that name spelling must match across every document in the set. Before starting, check that names are spelled identically to the passport or ID card on every page, then confirm with the receiving body whether it wants an original, a certified copy or a certified translation, then count the number of certified sets needed before work starts, because extra sets restart the certification steps. The specifics here are document type: Contract; location: Ayutthaya, and those decide which translation and certification level applies. The terms that frame this page are employment · contract · salary · letter. After certification, scan the full set before it leaves your hands. With a fixed filing date, count backwards from it and book each certification step in reverse. If multiple certified sets are needed, order them all in the first round to avoid re-queuing. High-resolution photos of seals and signatures help when the destination asks for re-verification. Record the reference number of each certification layer; it is the fastest way to trace status. Foreign documents used in a work permit or incorporation file — degrees, experience letters, the parent company's certificate of incorporation, powers of attorney and passports — must be translated into Thai or English as the office requires and certified along the correct chain: certification in the country of origin, then embassy or Department of Consular Affairs legalisation as applicable. 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.
