Hi, what's the earliest you can extend your stay? We entered visa exempt and want to extend. We would like to do it in samui and will of been in Thailand two weeks, so half way through and want to extend before travelling around. Also what paperwork is needed now please.
Thanks in advance
TLDR : Answer Summary
To extend a visa-exempt stay in Koh Samui, you can only apply for a tourist extension during the last week of your permission to stay, typically around 5 days before your stamp expires. This is different from many other locations in Thailand where you can apply when you have 30 days or less remaining. Ensure to prepare all necessary paperwork for the extension process.
