Yes they do but when people try to max out 60 or 90 days and didn't count arrival day and have a non changeable return ticket on day 61 or 91, no not the whole world I know but still not good when they see the last day stamp.
Immigration Officer wrote me some kind of letter (not a residence certificate) with my photo on it to bring to any bank to be able to open an account before I got my 1 year extension. I choosed Kasikorn because I've heard from many people that it's the easiest bank to be able to open a bank account and it was. You must also have a Thai phone number connected to your passport, I did that at a regular phone shop.
This time for 2 months I transferred what they asked me to do, 65 000, then IO told me to instead have 67 000 baht per month into my account following 12 months.
Okay thanks then i misunderstood about normal fees but as long as I get my extension I will not ask or argue with Immigration Officer, I'm happy to be able to stay long term without hassle.
