The filing and pendency of a request for reconsideration shall not operate to stay the effectiveness of the decision involved unless so ordered by the Director or an Appeals Board. A request for reconsideration need not be filed to exhaust administrative remedies.36 FR 7186, Apr. 15, 1971, as amended at 58 FR 4942, Jan. 19, 1993; 75 FR 64663 , Oct. 20, 2010
