Stay legal: compliance habits for long-stay holders
Thailand is welcoming when your paperwork matches your behaviour. These obligations apply across most long-stay categories. Privilege and some LTR tiers simplify reporting, but they do not remove TDAC or overstay rules.
TDAC every entry
Complete Thailand Digital Arrival Card within 72 hours of landing at air, land, and sea checkpoints, including Elite, LTR, and retirement visa holders returning from short trips abroad.
TM30 address registration
Hotels usually file TM30 for you. In apartments and condos, the owner or juristic person must report your address within 24 hours. Missing TM30 blocks extensions.
90-day reporting
Many long-stay visa holders must notify immigration every 90 days online or in person unless their tier uses annual reporting (some Elite and LTR members).
Overstay penalties
Overstay fines run 500 THB per day up to a 20,000 THB cap. Even one day creates an immigration record and can affect future visa applications.
For 90-day reporting help, see 0. For border-run risks and enforcement trends, read 1.
Common mistakes
These errors show up repeatedly in our Bangkok consultations for marriage visa thailand cases.
- Unregistered marriage abroad without Thai legalisation
- 400,000 THB deposited the day before the immigration appointment, timing matters
- No TM30 when extending: extension denied
- Leaving Thailand without re-entry permit on single-entry visa
- Assuming marriage to a Thai grants work rights, it does not
- Applying with incomplete financial or relationship evidence on the official checklist
