Sorry, stupid question but I just can't remember: For the 30day extension on SETV, do I need some proof of where I'm staying (hotel receipt, etc.) or do I just input the address on the form?
TLDR : Answer Summary
For a 30-day extension on a Single Entry Tourist Visa (SETV) in Thailand, you typically only need to provide your hotel address on the extension application form. This is sufficient according to community members, so a hotel receipt is not required.
