Confused about two items regarding METV.
1) does it become active the day the consulate/embassy puts it in my passport or the day I enter Thailand?.
2) if I am reading the information right I have to leave the country every 60 days to extend it. Can I extend it in Chiang Mai or do I have to do a border bounce 3 times to get like 8 months out if it.
TLDR : Answer Summary
The METV (Multi-Entry Tourist Visa) becomes active the day you enter Thailand, not when it is issued by the consulate or embassy. Each entry allows you to stay for 60 days, which can be extended once for an additional 30 days at a local immigration office. After that, you will need to leave Thailand, perform a border run, and re-enter to obtain another 60-day entry stamp. It is advised to get the METV as close to your arrival date as possible to maximize your stay.
