FYO
I went to Surat Thani immigration today for my yearly extension of non o retirement visa..
Documents needed:
Bank statement for last 3 months (obtained today)
Bank letter (obtained today)
TM7
Photocopy of every page in passport and bank book
1 x photo
Hand drawn map of my house
Photocopy of house book
Very helpful staff who informed me if using orange savings book ( Bangkok bank) for proof of funds then bank letter and statement can be a week in advance. If using the blue current account book then the letter and statement must be obtained on the same day. Next year they want a print out from google maps of the residence with longitude and latitude and the hand drawn map plus 2 photos of the house.
I know it varies a little from office to office but hopefully this maybe useful for anyone using Surat Thani immigration.
Happy New Year to all 🙏🏼
