A certificate of enrolment — what should you know about the certification chain?

The scope of this answer is “A certificate of enrolment”, so it flags what usually causes documents like this to be rejected before summarising the general practice. Once the set is complete, check it line by line against the destination's own checklist before filing. The specifics here are document type: Enrolment, and those decide which translation and certification level applies. The terms that frame this page are certificate · enrolment · know · certification. What changes the timeline most here is whether the source documents are complete on day one. The biggest risk in cases like this is doing the certification steps out of order, which forces a restart. Before starting, check that names are spelled identically to the passport or ID card on every page, then confirm with the receiving body whether it wants an original, a certified copy or a certified translation, then count the number of certified sets needed before work starts, because extra sets restart the certification steps. With a fixed filing date, count backwards from it and book each certification step in reverse. Documents with a short validity window should be produced as close to the filing date as possible. Keep a copy of every source document plus the receipt or docket from each step. Record the reference number of each certification layer; it is the fastest way to trace status. Prepare at least one spare certified set, since applications usually go to several institutions at once. Education files normally pair a transcript with a qualification certificate, and institutions check both together. 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. 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. ILC handles document work only — translation, certification of the translation, notarial signature certification and the legalisation run at the Ministry of Foreign Affairs and embassies. ILC is not an educational institution or a credential-evaluation body and cannot guarantee recognition or admission. 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.
