Can DTV holders get a thai drivers license? I read in some places that you need a work permit

What’s the process for changing an initial 2 year license to. 5 year ? How far in advance can this be done and what is required / steps to do alone. Located in Jomtien, initial license issued from Bangkok

Hello people, I wonder if someone could help me with this. It concerns my Thai drivers license.

For years I have been going to Thailand on a non immigrant B (business)visa. Buying goods for my business.

But now the consulate is only offering me a 60 day tourist visa.

Is it possible with this Visa to renew my 5 year Thai license for another 5 years? I obtained the licence in Pattaya.

I appreciate any help, thanks!
