Submitting a medium-of-instruction letter to the United Kingdom — how must it be translated and certified?

The point raised here is “Submitting a medium-of-instruction letter to the United Kingdom”, so it covers both the requirements attached to this document set and the order the steps must follow. If any requirement is still unclear, send a sample image to the receiving body before producing the full set. Degree titles, field names and grading scales follow the issuing institution's official wording rather than a fresh interpretation. Prepare at least one spare certified set, since applications usually go to several institutions at once. Public holidays and embassy closures move certification queues more than most people expect. With a fixed filing date, count backwards from it and book each certification step in reverse. Record the reference number of each certification layer; it is the fastest way to trace status. If the receiving body confirmed its requirements by email, keep that message with the file. A key variable is the filing channel (in person, agent or online), which sets the copy format to prepare. The common failure in this group of cases is a translation that does not match the certification type required. Before starting, keep a digital copy of every page, including seals and signatures, then make sure document numbers, issue dates and issuing-office names match across the set, then ask in advance which category of certified translator the destination accepts. The specifics here are document type: Medium; destination: Uk, and those decide which translation and certification level applies. The terms that frame this page are Submitting · medium-of-instruction · letter · United. A Thai educational document intended for overseas use is normally translated into the language the destination requires, then legalised by the Legalisation Division of the Department of Consular Affairs, Ministry of Foreign Affairs, and where the destination requires it, further legalised by that country's embassy or consulate. Many credential-evaluation bodies require the institution itself to send documents in a sealed envelope or through the institution's own electronic channel; an applicant or translator copy is not accepted as a substitute, so the body's own handbook must be read before translation is ordered. Thailand deposited its instrument of accession to the Hague Apostille Convention on 30 June 2026, but the Convention is not yet in force for Thailand, so consular legalisation through the Ministry of Foreign Affairs and the relevant embassy remains the working route; always confirm the current requirement with the receiving authority before filing. 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.
