Is it 100% sure that if I go to get my 30 extension on my 30 day exemption the new 30 days will start on the date that was stamped in my passport? (Entered on Nov. 22, given until Dec. 21st) I am in Phuket. Thanks in advance! Only asking because someone said the new 30 days would start the day I apply, which is not what I've been seeing here.
