An extension of stay — what should you know about work authorisation?

The case under review is “An extension of stay”, so it separates what is specific to this file from the standard certification chain. Record the reference number of each certification layer; it is the fastest way to trace status. If the receiving body confirmed its requirements by email, keep that message with the file. Once the set is complete, check it line by line against the destination's own checklist before filing. Before starting, count the number of certified sets needed before work starts, because extra sets restart the certification steps, then verify the source document is still within any validity window the recipient applies, then check that names are spelled identically to the passport or ID card on every page. When several certification layers are required, start with the slowest one. If multiple certified sets are needed, order them all in the first round to avoid re-queuing. The terms that frame this page are extension · stay · know · work. The common failure in this group of cases is a translation that does not match the certification type required. What changes the timeline most here is whether the source documents are complete on day one. A visa is not a work permit: employment of foreign nationals falls under the Royal Decree on Managing the Work of Aliens B.E. 2560 (2017), with work permits issued by the Department of Employment in a filing separate from the visa and extension. 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.
