I am going to be flying to the Kingdom in a couple of months with a Non O-A for the first time. I already have lease for a rental house in Chiang Mai but I have not lived in that house yet.
When I arrive, my understanding is to call my Owner/Landlord and inform him of my arrival. Depending on my arrival time, I may not talk with him until the next morning, and he is supposed to file my TM30 online. He lives in Bangkok.
What exactly do I have to do with Immigration after I arrive?
