It is hard to get through to many, that a retirement visa goes not exist. 🔥
You are correct, it is an extension of stay for 365 days for the purpose of retirement.
If one came here with a 90 day non-o, and you have the funds,
Your best bet is K bank. I have done my own yearly ext. of stay for 15 years, not much has changed, and still done for 1900 baht.
