A national of China applying for the Non-Immigrant B business/work visa — how should the supporting documents be translated and certified?

The point raised here is “A national of China applying for the Non-Immigrant B business/work visa”, so it separates what is specific to this file from the standard certification chain. The terms that frame this page are national · China · applying · Non-Immigrant. The specifics here are destination: Cn, and those decide which translation and certification level applies. 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. A key variable is the filing channel (in person, agent or online), which sets the copy format to prepare. The biggest risk in cases like this is doing the certification steps out of order, which forces a restart. Keep a copy of every source document plus the receipt or docket from each step. Note who signed each certification and on what date for later reference. Public holidays and embassy closures move certification queues more than most people expect. Plan the schedule with room for at least one review cycle at the receiving office. After filing, follow up on the cycle the office states rather than waiting past the deadline. 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.
