only if you are skirting the system does it cost that much. If you don’t deposit the appropriate amount in an account and you pay an agency to fund an account and make fake documents for you that’s what it cost for a 12 month extension. If you deposit the appropriate amount and do the extension yourself it cost 1900 baht.
I’ve read they are really cracking down on that sort of thing but no idea if that is true or working.
Ok, I re-read the post. Yes to get a proper extension for retirement you have to deposit 800K in a bank account. I did that and it stayed there for years. But then I switched visas and it’s no longer required.
