Fill out N-470 (Application to Preserve Residence for Naturalization Purposes) online
Form N-470 is used by lawful permanent residents to preserve their continuous residence in the United States for naturalization purposes while employed abroad. Without this approval, extended absences from the U.S. can disrupt the continuous residence requirement needed to qualify for citizenship.
How to fill out N-470 (Application to Preserve Residence for Naturalization Purposes)
Confirm eligibility before departure
Verify that you have been a lawful permanent resident for at least one year, have been physically present in the U.S. for at least one year after obtaining permanent residence, and that your employment abroad qualifies under the statute.
Enter personal and employment information
Provide your full legal name, A-Number, date of birth, current address, and date you became a permanent resident. Enter details about your employer, the nature of the employment, and the foreign country where you will be working.
Document the qualifying employment
Include a letter from your employer confirming the nature of your overseas assignment, your employment start date, and how the position qualifies under one of the statutory categories (U.S. government, U.S. research institution, American firm in foreign commerce, or qualifying international organization).
Submit before the one-year absence deadline
File the completed form with the filing fee and supporting documents before you have been continuously absent from the United States for one year. USCIS will adjudicate the application and issue a decision.
