ORS § 408.450
No person in the military or naval service of the United States, or any auxiliary corps thereof, while exercising any privilege in this state by virtue of having paid an annual license or privilege fee to any state board or commission for the right to practice a profession or engage in a trade, shall lose such privilege because of failure to pay any such fee for any subsequent year during the period the person is in such service, unless dishonorably discharged therefrom. Upon being discharged from such service under honorable conditions and upon written application within 60 days of such discharge, every such person shall be restored to former status with respect to any such privilege without the necessity of paying the then current license fee.
