No doubt this question has been asked many times previously - I apologise for my inability to find it via a search.
I am a UK passport holder, 67, but when not in Thailand I am in the USA.
I had a Retirement visa for several years, then the double whammy of COVID and the sudden, unrelated passing of my Thai missus, and I was not able to get back to Thailand in order to renew my Retired Visa before it expired.
Thai consulates seem to have changed the rules, only USA Nationals can apply for an O-A visa from a USA Consul. I am told that I must apply in my country of origin, UK. Not lived there for over 40 years, only visited once, briefly, in more that 20 years. I started the application process, but the online document verification system is difficult. I am working on it, but it would be much less tedious if I could simply go to Thailand, visa on arrival and then "convert" that to a Retirement pass.
Is that possible?
