If I did a boarder run by land from to Laos last summer to Thailand and then one to Cambodia in fall by land and then left Thailand again and stayed in Laos for 3 1/2 months and now it’s February Can I still enter Thailand by Laos I did 2 runs on separate boarders, would I still be able to go to Thailand one last time by land?
TLDR : Answer Summary
You can enter Thailand by land from Laos, as the rule permitting two free visa-exempt entries by land resets each calendar year. Since your previous border runs occurred last year, they do not affect your eligibility for entry this year.
