410.668—Extension of time to request reconsideration.

If a party to an initial determination desires to file a request for reconsideration after the time for filing such request has passed (see § 410.624 ), such party may file a petition with the Administration for an extension of time for the filing of such request. Such petition shall be in writing and shall state the reasons why the request for reconsideration was not filed within the required time. For good cause shown, the component of the Administration which has jurisdiction over the proceedings (see § 410.601) may extend the time for filing the request for reconsideration.
