An extension of stay — what should you know about the Apostille position?

The subject of this page is “An extension of stay”, so it covers both the requirements attached to this document set and the order the steps must follow. The deciding factor is the receiving body's requirement, not only the format of the Thai-side document. What changes the timeline most here is whether the source documents are complete on day one. The terms that frame this page are extension · stay · know · Apostille. Documents with a short validity window should be produced as close to the filing date as possible. Public holidays and embassy closures move certification queues more than most people expect. 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. After filing, follow up on the cycle the office states rather than waiting past the deadline. Keep a copy of every source document plus the receipt or docket from each step. Note who signed each certification and on what date for later reference. 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. 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. ILC's scope is documentation — certified translation, notarial signature certification and running legalisation at the Department of Consular Affairs or an embassy. We are not an immigration authority and cannot guarantee any visa decision, which rests solely with the competent officer. 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.
