I am pretty sure this has been asked before, but can't find a post with the answer; is it a sure thing that a Canadian doing a border hop by land, after being here on a thirty day exemption, then a thirty day extension, can get another thirty day exemption? I am planning to do this at Mae Sai crossing. Thanks in advance and HAPPY NEW YEAR!
TLDR : Answer Summary
A Canadian citizen who has utilized a 30-day exemption followed by a 30-day extension can re-enter Thailand and is eligible for another 30-day exemption via a land border crossing. However, it is important to note that only two land border visa exemptions are permitted per calendar year. The conversation also mentions the possibility of a tourist visa for longer stays in Thailand.
