Submitting a fit-to-fly medical certificate to the United States — how must it be translated and certified?

The issue to settle here is “Submitting a fit-to-fly medical certificate to the United States”, so it covers both the requirements attached to this document set and the order the steps must follow. The specifics here are document type: Fittofly; destination: Us, and those decide which translation and certification level applies. The terms that frame this page are Submitting · fit-to-fly · medical · certificate. The condition most often overlooked is that name spelling must match across every document in the set. What sets this case apart is the number of certified sets and the window in which they must be used. 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. When several certification layers are required, start with the slowest one. For documents going abroad, include international shipping time in the plan. Record the reference number of each certification layer; it is the fastest way to trace status. Attach a document index to the bundle so nothing is lost during review. Once the set is complete, check it line by line against the destination's own checklist before filing. A Thai-issued medical document intended for a foreign authority normally follows this order: obtain the original from the facility, have it translated by a translator the destination accepts, certify the translation at the Legalisation Division, Department of Consular Affairs, Ministry of Foreign Affairs, then obtain the destination embassy's attestation where required. Each step verifies only what falls within its own authority. A medical translation must preserve the diagnosis, disease codes, drug names, dosages, units and result values exactly as written — no rounding, no unit conversion, no summarising. Where the original is illegible handwriting, the facility should be asked for a typed version or a written confirmation rather than the meaning being guessed. Thailand deposited its instrument of accession to the Apostille Convention on 30 June 2026, but the Convention is not yet in force for Thailand. In practice the traditional route through the Department of Consular Affairs and the destination embassy still applies until entry into force is formally announced. Cost and lead time depend on page count, the density of clinical terminology, the target language and the certification steps required, so every file is quoted before work starts.
