(US Citizen) Are there official rules on the number of times you can enter without a visa? I was here in December last year and extended into January. I left for nearly 4 months and just came back. Border patrol had a lot of questions this time. Feeling lucky to have got in. Not sure if I am pushing the boundaries of entering without a visa. I will stay 28 days this time and was planning on coming back in December. So that would be 3 entries with one extension and one entry was in the previous year.
Also what happens if you are denied entry will I be able to just quickly book a flight and fly out a few hours later or will I need to sit in some detention center?
Should add I make money from US real estate investments and am a shareholder in a Nevada company. So very easy to prove I do not work here. And I never enter or exit by land.
TLDR : Answer Summary
US citizens can enter Thailand visa-free for up to 30 days via international airports if they meet certain conditions. However, frequent entries may raise suspicion, and border control assesses whether individuals are using this privilege appropriately. Expats should understand potential consequences of being denied entry, which may include immediate flight arrangements or possible detention.
