Can I get a 45-day visa on arrival in Thailand instead of the usual 30 days?

Yes, it is currently possible to receive a 45-day visa exemption upon arrival in Thailand instead of the usual 30 days for certain nationalities, a temporary measure in effect until March 31, 2023. Travelers do not necessarily need a return ticket; an onward ticket may suffice, although airlines may check for it before boarding. It is important to note that this is distinct from the visa on arrival, which requires an application and fee.
