Question about 30 day extensions:
Do they need to see the same list of requirements/documents as when you entered, like the special covid travel insurance for your proposed stay, etc etc?
TLDR : Answer Summary
To obtain a 30-day extension on your visa in Thailand, you generally only need your passport, a few copies, two passport photos, and a fee of 1900 baht in cash. While some may suggest proving accommodation and completing forms, the essential requirements are straightforward.
