Check your status and/or update your information here, especially if you've moved recently. (You'll need your license or ID card in order to make sure your address is right.) Even if you think you updated it when you moved, check now and make sure the change actually made it through the system!
Those in other states should also double-check your status *now*. I think the Oregon deadline is 10/16; other states are also probably in the next two to three weeks.
Doesn't hurt to be a little paranoid. Even the most well-meaning bureaucracy will screw up once in a while.
