Yes, but no need to leave 😉 You can enter on visa exemption, then extend that another 30 days for 1900 baht at a immigration office.
In Chiang Mai you can actually go to Immigration and extend immediately after you arrive and get total 60 days. CM probably has the “friendliest” immigration office in Thailand. When I did my extension there I was in and out in less than 30 minutes.
But there is two locations, go to the one at the Central Festival Mall. Rarely any queue there
You need:
- printout of TM 30 registration from your accommodation
- passport photo
- 1900 baht (cash only)
- passports, photocopies of passports and visa stamp
- prefill TM7 makes it faster, download at
