A transit visa — what should you know about the 90-day notification?

This question is specifically about “A transit visa”, so it flags what usually causes documents like this to be rejected before summarising the general practice. After certification, scan the full set before it leaves your hands. Keep a copy of every source document plus the receipt or docket from each step. If the receiving body confirmed its requirements by email, keep that message with the file. With a fixed filing date, count backwards from it and book each certification step in reverse. Public holidays and embassy closures move certification queues more than most people expect. 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. The terms that frame this page are transit · visa · know · 90-day. A foreigner permitted to stay beyond 90 days must notify their address to the competent officer under section 37(5) of the Immigration Act B.E. 2522, filed in person, through an authorised representative, by post, or through the Immigration Bureau's online system. Entry, stay and status of foreign nationals in Thailand are governed by the Immigration Act B.E. 2522 (1979) and its ministerial regulations: visas are issued by Thai embassies, consulates and the Ministry of Foreign Affairs e-Visa system, while permission to stay and extensions are decided by the Immigration Bureau of the Royal Thai Police. 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.
