My 90 day non-immigrant O retirement visa expires on Monday 19 Jan. That's the stamp date.
Day 60 since my 800k baht transfer into Kasikorn bank will be on Friday 16 Jan.
My plan is to go Friday morning to the bank with my bank book and get the necessary documents, then head straight to immigration in Chiang Mai with those and other necessary documents, etc, and apply for a 1 year extension.
If denied I will ask for an extra 7 days to sort things out. If denied the extra 7 days, I will travel to Laos via Chiang Rai on Saturday/Sunday. Come back on a visa exemption and apply again for a 1 year visa extension (or a 90 day visa if that's required first).
It's a tight window. Assuming my documents are in order, is there a reasonable chance of success? Or should I just plan to leave the country and come back and handle things with less time pressure?
