Going to immigration in Chiang Mai next week to extend my 60 day tourist visa for tourism purposes. Has anyone been recently? What docs are required? So far I have found form TM.7 which I fill out when I arrive, photo 4x6 cm, original passport, copy of passport and relevant pages, and a photocopy of departure card. I don't have a departure card, never received one, maybe I was sleeping on the plane when they were passed out. Is it required? Any advice appreciated. Thank you.
