Oregon only has the authority to suspend your right to drive in the State of Oregon. However, Oregon and 44 other states and the District of Columbia have adopted an agreement known as the Driver License Compact. Oregon will report the conviction to the home state of the driver (assuming the home state has also adopted the Compact.) Your home state will then generally take action to suspend your license.
This also works in reverse. If you are an Oregon licensed driver and you receive a DUII out of state, Oregon will likely suspend your license if it learns of the conviction.
Even if Oregon does not report your suspension (because you entered diversion), your home state may still learn of a suspension through the National Driver Register (sometimes referred to as the National Driver Registry). The National Driver Register (the "Register") serves as a central repository of information on individuals whose privilege to drive has been revoked or suspended or who have been convicted of serious traffic offenses. The records maintained in the Register consist of identification information including your name, date of birth, gender, driver license number, and the reporting state. The substantive information (the reason for the suspension or conviction and associated dates) resides in the reporting state. State motor vehicle departments can query the Register to determine if an individual's license or privilege has been withdrawn by any other state. All 50 states and the District of Columbia participate in the Register. You can request your record from the Register here.
