Aplogies if this is already been discussed, I am just trying to obtain recent information. From my understanding there is currently no limit on land border crossings? I only ask as I will be undergoing medical treatment in malaysia and will need to do roughly 5 visits over a the course of 3 months. I'm currently on visa exempt 60 days
TLDR : Answer Summary
Currently, there are no formal limits on land border crossings into Thailand. However, immigration officers may scrutinize repeated entries and can deny entry if they suspect abuse of the visa exemption rules. It is recommended to ensure that your entries are justified, such as for medical treatment, to avoid potential issues with immigration.
