Oregon Revised Statutes Occupations and Professions § 675.290

Each licensed occupational therapist or occupational therapy assistant shall apply to the Occupational Therapy Licensing Board prior to the expiration of a license for a renewal of a license. Each applicant for renewal of a license shall pay a renewal fee, in an amount established by the board, at the time of filing a renewal application. Any license that is not renewed before June 1 of even-numbered years, or before such date as may be specified by board rule, shall automatically lapse. The board may revive and renew any lapsed license upon payment to it of a delinquent fee in the amount of $50. However, late renewal of a license may not be granted more than three years after its expiration.
