Submitting an employment reference letter to South Korea — how must it be translated and certified?

The issue to settle here is “Submitting an employment reference letter to South Korea”, so it separates what is specific to this file from the standard certification chain. The terms that frame this page are Submitting · employment · reference · letter. The specifics here are document type: Experience; destination: Kr, and those decide which translation and certification level applies. Before starting, confirm with the receiving body whether it wants an original, a certified copy or a certified translation, then check that names are spelled identically to the passport or ID card on every page, then verify the source document is still within any validity window the recipient applies. A key variable is the filing channel (in person, agent or online), which sets the copy format to prepare. The deciding factor is the receiving body's requirement, not only the format of the Thai-side document. Note who signed each certification and on what date for later reference. Record the reference number of each certification layer; it is the fastest way to trace status. Public holidays and embassy closures move certification queues more than most people expect. For documents going abroad, include international shipping time in the plan. Some institutions accept documents only when sent directly by the school, so confirm the channel before translating. Education files normally pair a transcript with a qualification certificate, and institutions check both together. If any requirement is still unclear, send a sample image to the receiving body before producing the full set. 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.
