Unfortunately not. It does seem unfair that you did the right thing and are being penalised, as if you'd waited until late October to apply for your 60 day extension presumably you could have stayed until Christmas.
That's a lazy response. I saw the 500k baht 6-moth seasoned bank statement mentioned for tourists wanting to visit Thailand. No mention of it being in a Thai bank account.
Do you have a link that mentions both the 500k baht and a Thai bank account? The only news I've seen refers to it being seasoned for six months, and how are tourists going to have a Thai bank account?
Hopefully it'll only be for non imm holders. Tourists who didn't bother to do anything during the previous amnesty should be given the choice of paying 500 baht per day to stay, or leaving.
