What changed
- Aug 2026: proof of funds now asked more often (6 resident reports)
Who this is for
You entered Thailand on a Destination Thailand Visa (DTV) and want to stay past your first 180 days without leaving the country.
What to bring
- Passport with your entry stamp
- TM.7 extension form (filled in, signed)
- One 4×6 cm photo
- TM.30 receipt from your landlord
- 1,900 THB in cash
Step by step
- Go to Chiang Mai Immigration at Promenada Mall, 2nd floor. Doors open 08:30.
- Take a queue ticket for extensions, not 90-day reports.
- Hand over the documents. Officers sometimes ask for proof of funds; bring a recent bank statement.
- Wait for the stamp. Most residents are out by noon.
After the extension
Your 90-day report clock restarts from the extension date. Update your entry date in Ping so the countdown stays right.
