Form N-400 Guide: Green Card Holders Face New Naturalization Civics Test

USCIS now gives most new naturalization applicants the 2025 civics test, while people who filed before October 20, 2025 generally remain under the earlier 2008 version. The filing date controls which test applies.

The application is Form N-400, Application for Naturalization. It is the principal USCIS form used by eligible permanent residents seeking U.S. citizenship through naturalization.

The test is only one requirement. Applicants must also meet rules covering residence, physical presence, good moral character, English, and other statutory conditions.

The filing date determines which civics test applies

USCIS administers the 2025 Naturalization Civics Test to applicants who filed N-400 on or after October 20, 2025. Most people filing in 2026 should therefore prepare for that test.

Applicants who filed earlier generally remain under the 2008 civics test framework. A person’s test version depends on the filing date, not simply on when USCIS schedules the interview.

The civics requirement sits alongside the English requirement. Naturalization applicants must satisfy both, along with the other conditions for citizenship.

The five-year rule requires residence and time in the United States

The most common route covers a lawful permanent resident who has held permanent resident status for at least five years. USCIS says applicants using this pathway must satisfy requirements involving age, permanent residence, continuous residence, physical presence, and other naturalization conditions.

The ordinary rule comes from INA Section 316. Applicants normally must show five years of continuous residence immediately before filing.

They also need at least 30 months of physical presence in the United States during that five-year period. These tests overlap, but they are not the same.

Continuous residence asks whether the applicant maintained a principal dwelling place in the United States during the required statutory period. Physical presence counts the actual time spent inside the country.

Travel history can affect continuous residence. An absence of more than six months but less than one year can create a rebuttable presumption that residence was broken. An absence of one year or more generally creates more serious statutory consequences unless a qualifying exception applies.

Long trips require careful review. Applicants with substantial international travel should calculate their residence history before filing.

Some spouses of U.S. citizens may use the three-year provision

A separate pathway may cover certain permanent residents who have lived in marital union with a qualifying U.S. citizen spouse. The applicable period is three years, but marriage alone does not establish eligibility.

The analysis also considers the spouse’s citizenship period, the marital union, and the applicant’s residence and physical presence. Each condition must satisfy the applicable statute.

The three-year rule is therefore narrower than simply having been married to a U.S. citizen for three years. Applicants must examine the full set of requirements before relying on it.

Early filing is limited to 90 calendar days

Eligible applicants may file up to 90 calendar days before completing the required continuous residence period under applicable rules. The early-filing allowance applies only to the residence period.

It does not remove the other naturalization requirements. Applicants still must meet the applicable physical-presence, good-moral-character, English, civics, and other statutory conditions.

Timing matters. A person who qualifies for early filing still needs to confirm that the correct residence and travel calculations support the application.

Good moral character remains part of the review

Applicants must establish good moral character during the applicable statutory period and remain eligible throughout the naturalization process. USCIS may examine more than one type of conduct.

Criminal conduct, false testimony, tax issues, and other behavior can affect the analysis. Some conduct creates statutory bars, while other conduct may factor into the agency’s broader evaluation.

A completed application does not resolve those questions by itself. The applicant must continue to qualify through the process.

Filing the application does not end permanent resident status

Submitting N-400 does not automatically end a person’s permanent resident status. The applicant remains a permanent resident unless an independent event affects that status.

Naturalization is not complete when USCIS approves the application. Citizenship comes only after approval and completion of the required Oath of Allegiance.

The oath is the final required step identified in the naturalization process. Until then, the applicant remains in the permanent-resident stage.

A filing checklist for the eligibility review

1. Identify the pathway. Determine whether the application relies on the ordinary five-year provision or the special three-year marital-union provision.
2. Review residence. Check the required continuous-residence period and examine absences, especially trips lasting more than six months.
3. Count physical presence. Under the ordinary five-year provision, confirm at least 30 months in the United States during the relevant period.
4. Check the filing window. If using early filing, confirm that the application falls within the 90-calendar-day allowance and that the other requirements are also met.
5. Prepare for the correct test. Applicants who filed on or after October 20, 2025 generally prepare for the 2025 civics test. Earlier filers generally use the 2008 framework.
6. Review conduct and taxes. Consider criminal conduct, false testimony, tax issues, and other matters that could affect good moral character.
7. Complete the process. Approval alone does not confer citizenship. The applicant must complete the Oath of Allegiance.

The application opens the process. Residence, travel, conduct, English, civics, and the oath determine whether it reaches completion.
