Your First 90 Days: A Retirement Relocation Checklist

Back to Blog

The first three months after relocating set the tone for everything that follows. Here's a practical, month-by-month checklist.

Month 1: Foundations

• Complete your Thailand Digital Arrival Card and any entry requirements before travel
• Arrange temporary accommodation while you explore neighborhoods in person
• Open a Thai bank account (start this early — some banks require an embassy letter)
• Get a local SIM card and set up basic connectivity
• Register your address with immigration (TM30) if required by your accommodation

Month 2: Settling In

• Confirm your health insurance meets your visa category's requirements
• Register with a primary hospital or clinic for ongoing care
• Sign a longer-term lease or finalize a property purchase, once you've explored enough neighborhoods
• Start basic Thai language lessons — even a little goes a long way
• Join a local expat group or club to start building a social circle

Month 3: Making It Permanent

• Complete your first 90-day immigration reporting requirement
• Set up recurring household services (cleaning, maintenance, gardening if applicable)
• Coordinate estate planning and legal documents relevant to your new residency
• Plan your first visa renewal timeline well ahead of the deadline
• Revisit your budget against real, lived costs and adjust

Most of what makes the first 90 days hard isn't any single task — it's not knowing what order to do things in.

Week 1–2: Immediate Essentials

Open a Thai bank account — Bangkok Bank and Kasikorn Bank are the most expat-friendly, with English-speaking staff at major branches. You will need your passport and a local address (your hotel or condo contract works initially). Activate a Thai mobile number with AIS, DTAC or TrueMove — SIM cards are available at any 7-Eleven or phone shop for THB 300 to 500 with a generous data package.

Week 2–3: Immigration and Documentation

Register your address with immigration using Form TM.30 — your landlord or hotel typically handles this. Set your 90-day reporting schedule. If arriving on a tourist visa with plans to convert, consult with a visa specialist about timing and requirements for your Non-Immigrant O-A application. Collect certified copies of your passport, visa pages and entry stamp — you will need these repeatedly.

Week 3–4: Healthcare Setup

Visit your chosen hospital for initial registration and a comprehensive health screening. Compare health insurance options and secure coverage before your travel insurance expires. Register with a local dentist for a checkup and cleaning. If you take regular medication, establish a prescription routine with a hospital pharmacy — many medications cost 70 to 90 percent less than at home.

Month 2: Housing and Home Setup

If you arrived in temporary accommodation, this is the time to find your longer-term home. Visit multiple neighborhoods at different times of day. Set up utilities, internet (fibre broadband installation takes 1 to 3 days) and any household help you need. Purchase or arrange transportation — whether that is buying a motorbike, renting a car or confirming you are comfortable relying on Grab.

Month 2–3: Community and Lifestyle

Join at least one social group or club — the Chiang Mai Expats Club, a sports group, a volunteer organization or a hobby circle. Attend a few orientation events. Start a Thai language course — even basic conversational Thai dramatically improves daily interactions. Explore neighborhoods beyond your immediate area. Establish routines: morning market visits, a regular café, a fitness routine, a weekend day-trip pattern.

Month 3: Financial and Legal

Transfer and verify the required funds in your Thai bank account for visa purposes. Set up international money transfer arrangements (Wise, formerly TransferWise, is popular among expats for its low fees and fair exchange rates). Consult a legal advisor about a Thai will, power of attorney and any tax implications between Thailand and your home country. Review and finalize your health insurance after three months of understanding local healthcare costs.

Ongoing: Building Your Life

After 90 days you will have the infrastructure in place. The focus shifts from setup to enrichment — deeper friendships, new skills, travel within Thailand and the region, and fine-tuning your budget based on actual spending data. Many retirees say the first year is about discovering what Chiang Mai offers; the second year is about choosing what matters most to you.
