Can I do a back to back border run to Mae Sai in Thailand?

Yes, it's possible to do a back to back border run to Mae Sai. Participants in the discussion mention that you can make a border run followed by a 30-day extension at Immigration, allowing for multiple extensions if timed correctly. However, there are limits on how many border runs can be conducted without issues, particularly concerning the number of entries allowed within a specific timeframe.
