Form N-470 is used by lawful permanent residents who must leave the United States for employment abroad but wish to preserve their continuous residence for future naturalization eligibility. To qualify, the applicant must have already lived in the U.S. as a permanent resident for at least one year without extended absences and must be employed by a qualifying organization, such as the U.S. government, a U.S. company engaged in international trade, or a religious or research institution. Approval allows the applicant to remain eligible for naturalization despite long-term overseas assignments.
