Why are people concerned about the TDAC, if it's anything like the Singapore, Malaysian, Taiwan system it will mean arrivals a departures will be hassle free with no interaction with immigration officers. Unless of course you are playing the system.
Hi Mate, I did my visa in Savannakhet in December last year. My money had been in my account for more than 2 months. The document I followed stated something along the lines, that the 400k had to be in your account on the day of application, or the equivalent of 400k in an overseas account in your name. I'm trying to find that document at the moment, but I'm assuming that things have changed, and I should have kept my mouth shut. Have a good Songkran.
