I am finding it increasingly difficult to get/renew a US drivers license. I normally do not drive a car in Vietnam so I have no real need for a Vietnamese license. More to the point, a Vietnamese license is essentially useless when visiting the US -- especially for things such as renting a car (or getting insurance). My home state (and I guess, most others) wants to verify my in-state address -- which of course I no longer have. I use a mail-forwarding service, but it is not in my home state.
What have other people done about maintaining a US driver's license.
