Roughly 1 million green card holders naturalize each year. Pass rates on the civics test exceed 90%. The reasons applicants are denied or delayed cluster around three issues: physical presence, continuous residence, and good moral character.
Eligibility basics
- 5 years of LPR status (3 years if married to and living with U.S. citizen spouse)
- Continuous residence in the U.S. throughout
- Physical presence in the U.S. for at least half the qualifying period
- 3 months of state residence in the state of filing
- Good moral character throughout the qualifying period
- Basic English (read, write, speak)
- Knowledge of U.S. history and civics
- Attachment to the principles of the Constitution
- Willingness to take the Oath of Allegiance
Continuous residence — the silent denier
Continuous residence means LPRs maintained the U.S. as their primary residence. Trips abroad of:
- Less than 6 months: Generally fine
- 6 months to 1 year: Presumption of breaking continuous residence — must rebut
- Over 1 year: Continuous residence broken automatically (unless N-470 reentry permit)
USCIS looks at travel history holistically. Multiple 5-month trips abroad each year, while individually "fine," can collectively suggest the applicant doesn't really live in the U.S.
Physical presence — the math
30 months of physical presence in the U.S. during the 5-year qualifying period (18 months for the 3-year spousal track). This is calculated by counting actual days in the U.S. — every trip abroad shortens this.
Calculate yourself: List every trip abroad with departure and return dates. Subtract those days from 1,825 (5 years). The result must equal at least 913 days (~30 months) for the 5-year track.
Good moral character (GMC)
The 5-year (or 3-year) qualifying period requires GMC. Issues that affect GMC:
- DUIs and other criminal convictions
- Failure to file taxes or pay child support
- Selective Service registration (males 18-25 must register)
- Lying on prior immigration applications
- Persistent drinking/gambling reaching habitual levels
- Adultery in some interpretations (rare modern application)
USCIS typically reviews the qualifying period plus reasonable look-back. Older issues outside the period may still be considered if pattern continues.
The civics test
10 questions from a pool of 100, asked orally during the interview. Applicant must answer 6 correctly. Study materials are at uscis.gov/citizenship. The 2008 version of the test is currently in use; a redesigned version was proposed but pending implementation.
Special accommodations for older long-term LPRs:
- 50/20: 50+ years old, 20+ years LPR — may take test in native language
- 55/15: 55+ years old, 15+ years LPR — same accommodation
- 65/20: 65+ years old, 20+ years LPR — simplified civics test (20 questions, 6 correct to pass)
The English test
Applicant reads one of three sentences provided by the officer; writes one of three sentences read aloud by officer; speaks throughout interview. Officer assesses overall English ability.
The interview
Typically 20-40 minutes. Officer reviews N-400, asks about travel, employment, family, criminal history, tax compliance. Conducts English and civics tests. Decisions are often given same-day; complex cases continued for review.
The oath ceremony
Final step. Either same-day with the interview or scheduled within weeks. Applicant takes Oath of Allegiance, receives Naturalization Certificate, becomes a U.S. citizen. Immediately eligible to apply for U.S. passport, vote, sponsor immediate relatives.
