I'll try to make this as succinct as possible:
* 15Mar: Arrived BKK on a Non-O, staying in a private residence, TM30 submitted
* 25Mar: Got the "official" TM30 from immigration, this allowed me to open bank account, deposited 800K THB that day.
* 30May: Planning visit to immigration to get 1 year extension for Non-O
* 12Jun: Current Non-O stamp in passport expires
Questions:
* What do I need to do to have a smooth experience with immigration on 30May?
* I know I have to go to my bank and get...something??? Official letter? Stamp in my passbook? Something else?
* Do I need to do ANYTHING else other than proof of funds? Refresh the TM30? Etc?
I assume I can initiate this as soon as the funds have "seasoned" i.e. 2 months in bank. I don't want to wait until the last minute and have my current visa expire due to issues with immigration.
Thanks...
