Sean Paul Scarbrough you mean the one you can get within Thailand? It's called Non-O based on age over 50, valid 90 days and can be extended multiple times for 1 year at a time.
If you're over 50 you can get a tourist visa, then once in Thailand get a 90 days Non-O visa based on age over 50, then a visa extension for 1 year. Alternatively you can get a Non-OA visa for 1 year from your embassy, requirements are different though.
Thank you, very helpful. It might be the better option to come to Thailand on visa exemption and then apply for a Non-O visa within Thailand then. In this case I have to open a bank account while still on visa exemption, right? Is it possible without problems to open a bank account on visa exemption? Anny recommendation what bank is best?
