Dave Fletcher . . . you need to open the E-visa online application. You will be able to apply for the 90-days single entry Non-Imm-O retirement/over 50 visa. Just follow the lead. There is no need to take the Non-Imm-O/A visa. Embassy of Ottawa offers the Non-Imm-O visa! Check their website!
you don't seem to have understood the concepts of a "visa" and a "stay permit", or you wouldn't add your laughter smiley underneath all the correct information. I am out of my wits to explain why it is a FACT that a visa cannot get extended. And why Immigration still are "extending visa" and refuse to accept that they are actually not extending any visa π€£π
leave the 800,000 THB in your account until you have secured the Extension Of Stay with the 12.months transfers of 65,000 THB. Don't withdraw before the application to a new extension
the flight back home to aspply for a new OA visa every year, eats up the interest on your 800,000 THB would earn on a US bank. I never understand people who will rather pay 30,000 THB tea money to an agent to avoid having to put 800,000 THB into their Thai bank account (at SCB they pay me 1.25% interest!) and reason that they get more interest on a US bank, . . . . but then need to fly back home and back to Thailand every two years with a 1000.- to 1200.- USD flight ticket π
everything you wrote about the O/A and O visa is correct, except the part when you call the yearly extension of stay "visa extension". Immigration calls it the same, and they are wrong, this is very bad English and technically wrong. You don't get any visa extended - as in fact, you don't have a visa anymore from the point on when you got issued your first extension of stay - you just get your STAY PERMIT extended. A stay permit is not a visa
