Long-stay and lifestyle context
Many readers use this page while scouting Thailand for relocation or extended stays. Pair your plans with immigration status that matches how long you actually stay, not visa exemption alone.
Phase 1: Feasibility
Confirm your activity is not restricted under the Foreign Business Act. Evaluate BOI promotion if you need 100% foreign ownership. Budget capital, office, and four Thai employees per foreign work permit (standard companies)
Phase 3: Immigration
Directors and employees need non-immigrant B visa before work permit. Apply work permit at Department of Employment. BOI channel if promoted. 90-day reporting begins once long-stay visa affixed
Phase 4: Operations
Open corporate bank account: banks require registered company and sometimes physical office visit. TM30 reporting for foreign guests if you operate accommodation. Annual audit and tax filing. Thai fiscal year or calendar per registration
Common Pitfalls
Tourist visa " scouting " that becomes illegal work. Nominee shareholder structures: legally risky and immigration red flag. Registering in Bangkok but working from Phuket without branch registration

Practical planning matrix
Use this matrix alongside the sections above before you confirm dates, payment, or visa paperwork tied to your stay.
| Decision | Guidance |
|---|---|
| Stay length | Under 60 days may suit exemption or tourist visa; longer stays need DTV, Elite, LTR, retirement, marriage, or work permit routes. |
| Work activity | Tourism stamps do not authorise employment in Thailand. DTV, LTR, and work permit routes cover different activity types. |
| Family members | Dependents attach to primary applicant on Elite, LTR, and some marriage cases, not automatic on tourist entry. |
| Reporting | Confirm whether your visa uses quarterly 90-day reporting or annual reporting before you travel. |
| City base | Bangkok for immigration access; secondary cities for lower rent; islands for lifestyle with higher seasonal costs. |
Border-run warning: Leaving for a weekend abroad and re-entering on exemption is not a reliable long-term plan. Officers compare entry history. Plan a lawful long-stay category instead.
Where to live
City choice affects rent, social life, heat, and how often you deal with immigration in person. None of these places removes your visa obligations, but each has a different rhythm.
Bangkok
Most foreigners who work or raise a family in Thailand start here. International schools, hospital networks, and BTS/MRT coverage make daily life workable. Immigration offices and major embassies sit within reach for extensions and embassy runs.
Chiang Mai
Popular with remote workers and retirees who want a slower pace. Rent often runs 20 to 30 percent below central Bangkok. Immigration queues are usually shorter than Bangkok but still busy during peak season.
Phuket and islands
Beach provinces suit lifestyle-first relocators. Rents spike in high season, and many jobs are tourism-linked. Budget for air conditioning, transport, and occasional Bangkok trips for embassy or specialist services.
Hua Hin and Pattaya
Both attract large retiree communities within a few hours of Bangkok by road. Costs sit below Bangkok but above rural provinces. Either works if you want beach access without island logistics year-round.
For neighbourhood-level detail and retirement budgeting, see our cost of living guide.
Your first 30 days after arrival
Long-stay holders who get the admin right in the first month avoid painful fixes later. Work through this list in order where it applies to your visa.
- Complete TDAC within 72 hours of landing, even if you have done it on a previous trip.
- Photograph your passport stamp and note the expiry date. Set a calendar reminder two weeks before it ends if you plan to extend.
- Register your address. Confirm your landlord or condo juristic person files TM30.
- Open a Thai SIM and bank account if your visa path requires local financial proof.
- Buy or verify health insurance if your visa category requires it.
- Locate your nearest immigration office and check whether your visa needs 90-day reporting or annual reporting.

| Street meals | 60 to 120 THB |
| Modest expat monthly total | 40,000 to 80,000 THB |

Beyond tourism: local life and respect
Residents who stay a year or more usually branch out from the tourist trail: Thai language classes, neighbourhood markets, regional train trips, and local festivals. That is part of the appeal. It also means learning basic customs and understanding that visa rules on work still apply even if your employer sits in another country.
Public holidays and festivals change immigration office hours. Plan around the calendar in our Thailand festival guide.
