Any reason to renew my drivers license if I plan to move abroad?
If you’re living in Germany and you don’t have a valid license, US or otherwise, you won’t be able to drive (well you will, but you won’t be covered by insurance and anyway it’s just not a good idea!) Keep it simple, renew your current license and take it with you (duh). Be sure to check the residency requirements to make sure that your license is still recognised after X amount of time in Germany, as there is a limit to the amount of time you can drive on a foreign license.
If and when you move back to the U.S., you’d have to re-take the driver’s test if your license expires (there’s a 2-yr grace period for renewing a NY-issued license, not sure if it applies cross-state). Go to License X-Press at 300 W. 34th St. Also, if and when you visit, it’s much more convenient (and safe) than a passport for random places you need to show ID.
