I did that last year and CB Immigration-O said no good and threw in trash. I had a Thai with me for the next 3 trips at Immigration to finish a Non-O Ret on my own. She required a hand-drawn map.
Yes, same with me when I got the visa last year...but I tried online anyway and it worked. Did it on a Saturday before noon, and received the approval email about 4 hours later the same day...on a Saturday!! Just try it about 10 to 14 days in advance, and if it doesn't work you have plenty of time to go to the immigration office.
yes I use BK Bank and use the mobile app to pay, transfer, etc. I'll try the card-less feature next time. Thanks. But I'm not asking about ATMs in my OP, it's about the 800k and getting documents/letter for immigration. Planning to relocate later this year Hua Hin and Chonburi.
"...and keep no less than 400K baht rest of the year until you apply for next 1-year extension". If doing this, is there ever a requirement to go back up to the 800k, or only need to keep 400k and combined with the minimum monthly deposits of 65k continuing year after year??
