Hi! I have a METV and I know you can get a 30day extension for 1900 baht at Promenada in CM- but in my research it looks like it would be cheaper to just border run to Mae Sai? Is it compulsory to extend before running? Has anyone done the latter? What are your thoughts?
TLDR : Answer Summary
In response to the question, it is confirmed that it is not compulsory to extend your METV (Multiple Entry Tourist Visa) before making a border run. A border run to Mae Sai will provide an additional 60-day entry, which is more time compared to the 30-day extension costing 1900 baht. The overall costs for a border run are about 820-1138 baht, depending on the bus service, plus 500 baht for the border fee, making it a cheaper alternative but requires a day of travel.
