Where/how is permission obtained when required, and under what important circumstances can a stay be extended or changed?
Permission is obtained on arrival, at Thailand's immigration checkpoints, by submitting the application form available at the designated ports of entry with the photo, funds evidence, passport and onward ticket, and paying 2,000 Baht in cash in Thai Baht. Extension is the exception rather than the rule: visitors who enter with a Visa on Arrival generally cannot file an application for extension of stay, except in special cases of illness which prevent them from travelling, when the application can be submitted at the Office of Immigration Bureau, whose website the Embassy gives. The 2026 revision approved by the Cabinet lets those already in Thailand, and those travelling before the effective date, stay until the expiry of their permitted period, after which they may enter under the new schemes, a bilateral exemption, or an appropriate visa applied for through Thailand's e-Visa system.
