Expat Paperwork in Thailand — Complete Guide
Short answer first
Living in Thailand long term means keeping several obligations current: the extension of stay, 90-day address reporting, TM30 accommodation notification by the property owner, and re-entry permits before leaving the country. Missing any of them creates fines and complicates the next renewal.
Overall timeline: 1–3 weeks for a renewal cycle, then ongoing reporting
Documents to prepare
| Item | Detail | Status |
|---|---|---|
| Passport with current visa and TM6 details | Plus copies of every stamped page. | Required |
| Proof of address | Lease, TM30 receipt and, where required, a residence certificate. | Required |
| Financial or purpose evidence | Depends on the extension category: retirement, marriage, employment or study. | Required |
| Certified translations | For foreign documents such as marriage or pension records. | If available |
Step-by-step process
- Step 1: Review your current status
Confirm category, expiry dates and outstanding reporting.
Timing: Same day
- Step 2: Assemble the extension file
Financial evidence, address proof and category documents prepared and translated.
Timing: 3–10 business days
- Step 3: Immigration appointment
Extension of stay filed before expiry; attend in person.
Timing: 1 day
- Step 4: Re-entry permit
Obtained before any travel so the extension survives departure.
Timing: Same day
- Step 5: Ongoing reporting
90-day reports and TM30 updates whenever the address changes.
Timing: Every 90 days
Pitfalls and how to avoid them
Advice from real cases
- Diarise reporting dates a week early; online reporting can fail close to the deadline.
- Keep a single folder with every stamped page and receipt for renewals.
- Ask before switching visa categories — some switches require leaving the country.
