Just did this today at an agency aside from bank letter, statement bank book, yellow book, which I was informed of earlier now they wanted copy of chanote front and back as well as Wifes Thai ID. This is odd as I do the 800K which has been in bank since 2019.. After a discussion they upped the fee to 10,000 baht which I forked over.. I was quoted 7,000 for the service.. Not sure if this is bait and switch or what..
