itβs your problem after an accident, what you think Thai police is on your side??? They can figure out that itβs not legal ! But just do how you want and pay for it! I did by myself , just need the document from immigration thatβs it! I think I not even payed 400 baht ! All up to you !
First you need a permanent address confirmation, with this you and your Visa you go to immigration, they make some pictures and give you the form ( they help to fill out) after I got this document I went to bank , takes some signatures! In total it took me around 2 hours
