First, I apologize for yet another TM30 question but I have read for hours and still didn't find the answer.
So, on arrival (30 day stamp) I filled in the TM6 with the address I am staying at. Do I ONLY need to do the TM30 if I change my address/travel elsewhere. Obviously, I reported where I am staying on the TM6. I am staying at the house of my Thai friend in Prachuap, not a hotel.
I will be needing to extend for another 30 days.
Thank you in advance for your help.
