don't worry I have always an insurance, but I was courious if immigration ask it.
For example if you have a 1 year OA Visa, the health insurance is mandatory and immigration ask it when you enter. If your insurance cover only 3 months, they will give you only 3 months stamp in your passport.
Did it today in Samui, but could get only the 30 day for my TR60 visa. They said I can get the 60 days later. Someone know if I can apply the 60 days befor 29 january and add the 60 days to my 30 days extention which will expire 4th march? thx
