I would like to know when I can apply for the one year extension on my new Non-O retirement visa. My 800k baht has been seasoned already for Six months so not a issue. I have been told 2 weeks before my 90 Visa expires and also 1 month before by two different IM at my Nakon Phanom office. I would like to apply as soon as possible because I need to leave Thailand 3 weeks before the visa expires.
