A national of Switzerland applying for an extension of stay — how should the supporting documents be translated and certified?

The case under review is “A national of Switzerland applying for an extension of stay”, so the answer below starts with what this case actually needs before setting out the general rules. Note who signed each certification and on what date for later reference. Attach a document index to the bundle so nothing is lost during review. Plan the schedule with room for at least one review cycle at the receiving office. With a fixed filing date, count backwards from it and book each certification step in reverse. Once the set is complete, check it line by line against the destination's own checklist before filing. The terms that frame this page are national · Switzerland · applying · extension. The specifics here are destination: Ch, and those decide which translation and certification level applies. Before starting, ask in advance which category of certified translator the destination accepts, then plan the timeline so certification finishes before the real filing deadline, then keep a digital copy of every page, including seals and signatures. The common failure in this group of cases is a translation that does not match the certification type required. What sets this case apart is the number of certified sets and the window in which they must be used. Supporting documents issued abroad — police clearance, marriage and birth certificates, qualifications or financial papers — normally need translation into Thai or English by an accountable translator and the certification the receiving office specifies, usually legalisation at the Department of Consular Affairs and/or the issuing country's embassy. On Apostille: Thailand deposited its instrument of accession on 30 June 2026, but the Convention is not yet in force for Thailand, so the working route is still consular legalisation — the Department of Consular Affairs first, then the destination embassy. Fees and scheduling depend on the number of documents, the source language, which authority must certify them and the destination country; we confirm scope in writing before starting.
