I am going to Chiangmai for a week. I have not left Pattaya for an overnight stay since Covid days. I can't recall if I need to check in with immigration for the TM30.? I will be staying at a hotel. Thanks
what do you mean i need to do with my address?
TLDR : Answer Summary
When traveling within Thailand, specifically from Pattaya to Chiang Mai, you do not need to re-register your TM30 at the Pattaya immigration office if you are returning to your primary address after your stay. Hotels in Chiang Mai will usually register your address for the duration of your stay. After returning, ensure your TM30 records reflect your primary address for 90-day reporting, especially if you need to apply for immigration services.
