When did you become a permanent resident?

When the USCIS officer asks when the applicant became a permanent resident, the applicant should respond with the exact date of approval as printed on the Permanent Resident Card (Form I-551, commonly called a green card), which appears on the front under "Resident Since" and matches the date on the I-485 adjustment of status approval notice or the I-551 stamp in the passport for those who entered through consular processing abroad. The N-400 application requires this date in Part 1.

The date of permanent residence is critical because it starts the clock on the residency requirement: 5 years for most applicants (60 months from the green card date to the day before applying), 3 years for spouses of U.S. citizens (36 months), or 1 year for certain military spouse categories. Applicants can file the N-400 up to 90 days before the residency requirement is met (the so-called early filing window). For example, an applicant whose green card date is January 1, 2020 may file an N-400 as early as October 3, 2024 (90 days before the 5-year anniversary on January 1, 2025).

The applicant must also have been physically present in the United States for at least half of the residency period (30 months for the 5-year rule, 18 months for the 3-year rule). Applicants who became permanent residents while outside the United States (consular processing) have the date stamped in their passport and the green card mailed to their U.S. address. Applicants who adjusted status from a nonimmigrant or other status (Form I-485) have the approval notice and the green card mailed to them. The date is the same in both cases.

Applicants should bring the green card itself, the I-485 approval notice or I-551 stamp evidence, and the passport with any related stamps. Applicants whose permanent residence was conditional (a 2-year card from a marriage less than 2 years old at time of grant) must have removed conditions through Form I-751 before applying for naturalization. The 2-year conditional period counts toward the residency requirement. Applicants who have a 10-year card (received either originally or through I-751 approval) can apply for naturalization based on the original conditional admission date if applicable.

Applicants whose status was originally as a refugee or asylee have special rules for the start of permanent residence: time as a refugee or asylee in the United States can count toward the 5-year residency requirement under section 209 of the Immigration and Nationality Act. The applicant should consult an immigration attorney if there is any doubt about the date.
