Hi all, im a uk citizen aged 58 I will be applying in October for my non I'm O-A visa in London, I know from reading on here that I can get the visa for 1 year and then get another 1 year out of it by leaving and then re entering Thailand before it's expiry date, when that 2nd year is due to expire could I go to immigration and get a 1 year extension? I will be living in khon kaen
many thanks for all and any help
