If you happen to find yourself in the need of an international driving permit, this is what you must do. It is very easy and painless. First…go get some passport pictures taken. Then fill out the form found here. Then, package it up with your picture and a check for $15.00 and a seperate check for a flat rate envelope to be mailed international, it is a little more than $28.00 (check the usps post office for official rates)
Mail it to the address below

It is great to have one of these, you can drive most anywhere in the world and the turn around time is a little under 3 weeks.
Good luck and happy driving.
