Currently in Thailand , asking advice on the best option for obtaining an International Drivers Licence, I know I’m in good hands here , thank you kindly

Seeking advice about acquiring an international drivers permit!

Hi all,

I am a U.S. citizen from Oregon traveling to Phuket, Thailand in August. I lived in Phuket for 15 years, but have never needed a license there due to being underage. But now I am returning with the intention of renting a car to get around the island, and I was wondering if anyone had any advice on what are the steps to obtaining an international drivers permit? Are some companies better than others? How long does this process take? What should I expect to pay?

I appreciate all and any help! Thank you.
