A standard company employee work permit — what should you know about document translation and certification?

The matter being asked about is “A standard company employee work permit”, so it separates what is specific to this file from the standard certification chain. Attach a document index to the bundle so nothing is lost during review. High-resolution photos of seals and signatures help when the destination asks for re-verification. After certification, scan the full set before it leaves your hands. 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. Plan the schedule with room for at least one review cycle at the receiving office. When several certification layers are required, start with the slowest one. The terms that frame this page are standard · company · employee · work. The biggest risk in cases like this is doing the certification steps out of order, which forces a restart. Check first whether the issuing office of the source document is one the destination recognises. 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. Thailand deposited its instrument of accession to the Apostille Convention on 30 June 2026, but the Convention is not yet in force for Thailand, so embassy and Department of Consular Affairs legalisation remains the working route. 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.
