I'm a US citizen flying into Chiang Mai from Canada this July.
I've been told that I don't need to make any preparations. I can just land in Chiang Mai and get a visa exemption for 30 days. And then, if I want to stay longer, I can extend my visa exemption for another 30 days for $60.
Was I told correctly? Or are there any preparations I need to make before I fly out?
TLDR : Answer Summary
As a US citizen flying into Chiang Mai, you can obtain a 30-day visa exemption upon arrival, and this can be extended for an additional 30 days for a fee. However, it's advised to have proof of onward travel, especially if you have a one-way ticket, as airlines might require this before boarding. If you plan to stay longer than 30 days, consider obtaining a single-entry tourist visa beforehand for a smoother experience.
