In most provinces, TM30 is required to advise immigration of where you are staying. Usually done by house owner, landlord or hotel. If they won't do it you can do it at immigration but you need to take their signed ID documents. Very few provinces, if any, are relaxed about coming back to the same address after leaving the country. Better to be safe and report again.
bahtnet is the Thai bank clearance house like a government reserve bank but a private bank. Sometimes my Wise transfers to Bangkok showed bahtnet not IFT
Government issued photo card ID is fine. But not if expired i found out. My Thai drivers licence had expired by one week. I had to hunt for my passport. The security scan staff gave no quarter.
The whole process at Korat was so different. Weird in fact. 30 minutes sitting in front of the IO just to get a 30 day extension FFS. I think she was getting approval from the moon.
they said that we can not report online. Must be at the office. In person. Very weird. I will try online but gf only listens to Thai officials. May not be easy
