American Mariners Job Protection Act - Amends federal shipping laws that require a determination by the Administrator of the Maritime Administration regarding the non-availability of qualified U.S. flag capacity to meet national defense requirements before the head of an agency responsible for the administration of navigation or vessel-inspection laws is authorized on its own initiative to waive compliance with such laws when it considers it necessary in the interest of national defense. Requires the Administrator, in making such determinations, to: (1) identify any actions that could be taken to enable such flag capacity to meet the national defense requirements, (2) provide each such determination to the Secretary of Transportation and the head of the agency for which the determination is made, and (3) publish each such determination on the Internet site of the Department of Transportation (DOT) within 48 hours after it is provided to the Secretary.
Directs the Secretary to notify Congress of any waiver requests or issuances. Requires the notification of the issuance of a waiver to include the reasons why: (1) the waiver is necessary, and (2) specified actions are not feasible.
