I'm sorry if this is a repeat question but I've been looking and can't seem to find an answer any where. I have a question about the border run to Mae sai. It says that you can make a land border run twice a year but does that year start when you first enter Thailand or is it in a calendar year (starting on Jan. 1st). I made a run in December (2018) and in February (2019). My question is can I do another border run in April? Thank you in advance!
