Good to know. I was with my pal the other day and he was asking about getting a local license - he has Singaporean DL. I may have given him wrong info lol
It was a couple of years till I had one to do in Bangkok during Covid. Before that travelled for work. The admin staff at work dealt with it. I remember some people being baffled as they never knew it was a thing previously.
I have read different to this in a Chiang Mai group - the method of reporting resets too if you re-enter so fist 90 day after entering always has to be in person. A couple of provisos here 1) Chiang MaI dos have some peculiarities in their immigration office 2) When I have completed my 90 day I always did it in in person it at Jomtien as it is efficient and there is a good pie shop nearby :-)
As you are in USA and have time I would apply there in your home country. Visas from neighbouring countries have recently come under a little more scrutiny by some Immigration Officers.
