brought my passport with my one year extension and my lease agreement

Which visa? Non immigrant O?

Go to immigration, get a residence certificate and open another bank account at another bank. Bangkok bank froze my account, went to kasikorn and was using their banking app within a few hours. My transfers with Bangkok bank took 3 to 5 days. My new Kasikorn account transfers are complete in 3 to five seconds. I had other ways of getting money thankfully, but i won't get caught with only one Thai bank account again.

exactly

Like mentioned, use the official site and your name in your passport needs to match the name on your application 100%.

@Graham *****

since the US embassy doesn't verify income, how does he do that for his first extension of his non O?

Visit and do a little research.

if you're applying with a US passport, no. You need the 800k baht in a thai bank account

Get the non O from home and save yourself a lot of hassle. Just need 800k baht to deposit when you get here
