I don't think they're afraid of losing a comparatively few foreign customers, but if you've been booted from one bank, would another bank be keen to take you on?
Interesting. I'm certainly not, but I set my account up totally correctly, have never used an agent, never used the dodgy 800k method, and when summoned months ago for facial recognition scans I attended without fail. If you actually believe that other banks won't be auditing their accounts in the future, that's good for you! However, this is a worldwide shake-up and a lot of misinformed expats actually believe it's only Bangkok Bank!
Bangkok Bank will email the twelve month statement. I've done it for the last two years extensions. Much better than the clunky old system where you had to go into the branch, order the statement, then return five days later to pick it up. It's now delivered within a few hours to your email. Print it and take it to immigration for your extension. Too easy. Thank you Bangkok Bank!
