Employment experience letters for a work permit file in Ayutthaya — how are they translated and certified?

The scope of this answer is “Employment experience letters for a work permit file in Ayutthaya”, 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. The specifics here are document type: Experience; location: Ayutthaya, and those decide which translation and certification level applies. The terms that frame this page are Employment · experience · letters · work. 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. When several certification layers are required, start with the slowest one. 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. The point to fix before starting is the real deadline, so the steps can be scheduled backwards from it. The biggest risk in cases like this is doing the certification steps out of order, which forces a restart. 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.
