As mentioned above, I exited Thailand and re-entered the next day, but using visa exempt. I doubt I could obtain a Non-O visa "in one day" outside of Thailand. You are correct, however, that if I had obtained a Non-O outside Thailand, it would already meet the 800K requirement. That said, I have my doubts that 800K sitting in a Thai bank account could be used to obtain the Non-O outside Thailand. Maybe I am wrong about that,
