Have the rules changed regarding the number of land border crossings into Thailand?

The rules regarding land border crossings into Thailand have indeed changed in recent years. Previously, there was a restriction allowing only two land border crossings per calendar year, which was abolished in 2024. However, enforcement has tightened recently, and while immigration officers largely decide on entry permissions, there may be a 14-day visa on arrival applicable after the second crossing. This applies at their discretion, meaning some travelers may be questioned, especially those crossing frequently.
