Thank you for all the information provided on this page, very useful.
If I was to apply for the SETV for 30 days on arrival, would I be able to apply for an additional 60 days on arrival, or do I need to wait until a later time to apply for an extra 30 days (to a total of 90 days).
I am trying to figure this out before I buy a plane ticket, and book a hotel.
Thank you so much
TLDR : Answer Summary
The Single Entry Tourist Visa (SETV) grants you an initial stay of 60 days upon arrival in Thailand. After this period, you can apply for a 30-day extension. It is clarified that there's a distinction between 'visa on arrival' and the SETV, which is crucial to avoid confusion. Extensions are granted at the discretion of the immigration officer, leading to concerns about potential denial based on subjective grounds.
