Do I have to get a tourist visa upon arrival or can I just wait 30 days and find out what I want to do when I'm there (probably get a non immigrant b visa within within a within a couple weeks if i find work) Also where is the closest place to to koh phangan to get a visa/extensions, is is it koh samui? Thanks
TLDR : Answer Summary
You can enter Thailand with a 30-day stamp without needing a tourist visa in advance, but it's advised to obtain a proper tourist visa from a Thai embassy for a longer stay (60 days) if you plan to look for work. The closest location for visa extensions while on Koh Phangan is Koh Samui, where you can apply for a 30-day extension after your initial 30 days. Additionally, it's recommended to consider a Multi-Entry Tourist Visa (METV) for more flexibility and an extended stay, useful for job hunting.
