Thank you for your help
my question is I went to the border and got a 30 day tourist visa last month expires on December 26
can I go to the immigration office by the airport here in Chiang Mai and get a 30 day extension this week?
and also next question is would it be extended from the December 26 when my visa runs out?
I will probably go on December 12 which is around two weeks before it expires
Thank you for your help
