The Long Term Resident (LTR) visa — what should you know about the Apostille position?

The matter being asked about is “The Long Term Resident (LTR) visa”, so it covers both the requirements attached to this document set and the order the steps must follow. Attach a document index to the bundle so nothing is lost during review. Record the reference number of each certification layer; it is the fastest way to trace status. The next step is confirming the filing channel and the copy or file format required. Before starting, make sure document numbers, issue dates and issuing-office names match across the set, then keep a digital copy of every page, including seals and signatures, then plan the timeline so certification finishes before the real filing deadline. Leave buffer time in case a translation has to be amended or a source document re-issued. Documents with a short validity window should be produced as close to the filing date as possible. The terms that frame this page are Long · Term · Resident · visa. The point to fix before starting is the real deadline, so the steps can be scheduled backwards from it. Check first whether the issuing office of the source document is one the destination recognises. 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.
