A national of Russia 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 Russia applying for the Non-Immigrant B business/work visa”, so the answer below starts with what this case actually needs before setting out the general rules. After filing, follow up on the cycle the office states rather than waiting past the deadline. 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. When several certification layers are required, start with the slowest one. If multiple certified sets are needed, order them all in the first round to avoid re-queuing. Before starting, make sure document numbers, issue dates and issuing-office names match across the set, then keep a digital copy of every page, including seals and signatures, then plan the timeline so certification finishes before the real filing deadline. What changes the timeline most here is whether the source documents are complete on day one. What sets this case apart is the number of certified sets and the window in which they must be used. The terms that frame this page are national · Russia · applying · Non-Immigrant. The specifics here are destination: Ru, and those decide which translation and certification level applies. 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.
