During the two-year period that ended July 1, 1990, the Service issued Northern Marianas Identification Cards to aliens who acquired United States citizenship when the Covenant to Establish a Commonwealth of the Northern Mariana Islands in Political Union with the United States entered into force on November 3, 1986. These cards remain valid as evidence of United States citizenship. Although the Service no longer issues these cards, a United States citizen to whom a card was issued may file Form I-777, Application for Issuance or Replacement of Northern Marianas Card, to obtain replacement of a lost, stolen, or mutilated Northern Marianas Identification Card.
