I was planning to enter Thailand on a Visa Exemption, get 60 days permission to stay and convert to a non-imm O as quickly as possible and then extend for a year. I have British nationality. So, I was planning to buy a return ticket from the UK with a return flight perhaps 5 months in the future. I know immigration at the border have the right to check to see if you have a ticket out within 60 days before stamping you in. Are they actually checking at Suwannaphum?
