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.
TLDR : Answer Summary
The TM30 form is required to be submitted by the property owner (in this case, your Thai friend) within 24 hours of your arrival. You, as the foreigner living there, share responsibility to ensure that this report is completed. If you do not change addresses after your initial TM6 submission, you do not need to submit a new TM30. However, extending your stay may still require adherence to other immigration rules.
