thanks Tod. Yes I knew that, thanks. I just wondered if, like the banked 800,000 baht, if I fail to meet the requirements during my extension that it may put me in overstay or cancel it.
probably because you notified your address when you got the extension. All aliens with permission to stay in the Kingdom of Thailand need to report their address every 90 days. If you got a 60 day extension you reported your address then. If you get another 60 day extension, you are still reporting your address within 90 days.
