Important rules for foreigners
- Registration of residence (TM30)
All foreigners staying in Thailand for more than 24 hours must be registered by the property owner with the immigration service. This rule applies to those renting a property, staying in guesthouses, or living with friends.
How to submit TM30:
- Online via the immigration service website.
- In person at the nearest immigration office.
- Through the landlord (usually, hotels automatically handle this).
- 90-Day report (for long-term visas)
Foreigners staying in Thailand for more than 90 days on long-term visas (Non-Immigrant O, B, ED, O-A) must notify the immigration service of their current address every 90 days.
Ways to submit the report:
- In person at the immigration office.
- By mail (the application must be submitted 15 days before the deadline).
- Online via the immigration service website.
- Visa extension
Depending on the type of visa, foreigners can extend their stay:
- Tourist visa – extension for 30 days.
- Work visa – extension for 1 year with a valid contract.
