I entered Thailand about a month ago via land, but only stayed for 2 days. I plan to enter again via land as a border run so
likely less than 1 day.
Does this mean my 2 land entries for the year will be used up? Or do you think I will be allowed more because I will not have spent any significant amount of time in the kingdom?
TLDR : Answer Summary
When entering Thailand via land, the two entries per calendar year for visa-exempt nationals will be counted regardless of the length of stay. Therefore, even if the traveler only stays for less than a day, both land entries will be used up in the current calendar year.
