shouldn't make any difference. My bank account (Bangkok Bank) was originally set up in Udon Thani when I was living there. Now live in Nong Khai and the Bank there now supplies all my info for immigration. I have changed my address with the bank. So even though my account is still with Udon bank, they have my Nong Khai address.
In theory it should replace the need for a certificate of residence from immigration. But as this is Thailand, sometimes it will then sometimes it won't.
thank you for your reply. I did not realise that. So I suppose a follow on question, does it cause any problems if the account is in a different province. I know that the bank charges for out of province withdrawals, but that is overcome by doing cardless withdrawals. The main concern for me is that there are no problems when it comes to the yearly extension.
