Keep trying different Bangkok Bank branches. Depends on the person working there. I was able to open one on a student visa but i had to buy insurance from them. Or try an agent.
Officially with the dtv or student visa you are not allowed to open a bank account but many people are successful at Bangkok Bank
I've googled for this one I could not find if I can get it while I'm in Thailand. Now I'm actually afraid that they won't let me in so even thinking of canceling my ED visa before i leave.
Okay thank you. Yes started class november. I asked my school if it would be a problem and they said no. Then i will delay my family visit after the visa ends just to be sure.
