It’s my understanding that you have to fill out a TM28. The landlords complete the TM28. You should call because that part of immigration is open on the weekend in Chiang Mai. Don’t know about other BKK.
OIC..but would you need police clearance if you already had a O-A Visa? My husband’s visa ran out because we had to switch direct deposits to the Bangkok Bank. It’s been two months. We can now show the deposits coming in their banks.
