Australian living in Thailand for the last 3 years with Thai wife, i have getting by on multi entry spouse visas (as i was under the age of 50) which i obtained from Australia each time (new Visa issued each time, not an extension) . Now in my early 50's if i wish to apply for a 1 yr Retirement visa Non-O, how much cash do i need in the bank and for how long? My current spouse visa doesn't expire until January. Any advice appreciated.
