What should I do for my 90-day report in Thailand if I'm traveling and don't have a permanent address?

For your 90-day visa report in Thailand, you can use the address of your current accommodation, such as a hotel or Airbnb, at the time of reporting. Ensure that the establishment files a TM30 form for you, which registers your address with immigration. If you're staying in a hotel, they typically handle the TM30 process, while short-term Airbnb rentals may only be able to register you if your stay exceeds 30 days.
