Why was my first Non-O visa refused due to the 800k bank requirement?

I recommend you using service renewal visa.

I had to use a person to get this done. Mine was a marriage visa but she pulled some strings. I did have to pay 5000 for a covid extension but she was able to get the money thing worked out.

I applied for first time non-0 retirement in Bangkok last year and had the same issue. Was a few days short of having 800K 60 days on my account and my application was rejected. As I would be without stay permit the next day, it was suggested I got a Covid-19 extension (with two weeks "under consideration" first). So I did. Reapplied for Non-O another 2 weeks later (therefore didn't use the entire covid extension). This time succesfully. (But needed 4 visits to immigration within one month!)

NB for extension one year later, the requirements for bank saldo are stricter. Easiest to keep 800K minimum in your account continuously (there is a defined middle period where you can be lower, but never below 400K). All transactions over the entire previous 12 months will be checked (this happened in my case at least).

Pay agent tik tok jontien to do for you easy baht though

They have no qualms at all accepting the agent applications with zero evidence of funds. As long as there is a nice under table payment.

There is no seasoning requirement for funds when applying for a in country non O visa based on being over 50. The funds must be shown to have come from overseas.

If the IO is telling you different he’s wrong, but not sure if there’s anything you could do about it other than politely request to see a supervisor.
