In Bangkok they came the very next day after application, they took pictures of me, with me, and me holding up rental contract and bankbook readable. Polite and no "fee".
This was only after first non-O. Visa, for 1y ext no visit for me.
Notice that you need to do it in your home immigration office, if you're in different province you first would need to register be address, having temporary TM30 was not accepted. I didn't find that particular information mentioned anywhere, but seems to be the rules...
You just need to get letter from your embadsy stating that you've stated that the address they stated is the address you've stated that you reside at. Yes. And you need the embassy to write a letter saying that your passport is your passport. Lol. Yes. It sounds ridiculous, but that's what is to it unless you're working you're better off going to bangkok bangkok. Other banks often require work permits.
