Hi all, thanks for letting me join your group....i will be taking early retirement in October this year, I will be applying for a non immigrant 'O A' visa, I will apply at the Thai embassy in London, I have all the financial requirements already in place. I have to get a police check closer to the time, my question is do I only have to do this once, or each time I renew or extend the visa? I will be living with my girlfriend in khon kaen. Many thanks for any help and apologies if this question has been done to death before.
