Many immigrants use 'residency' and 'citizenship' interchangeably, but they are legally distinct statuses with different rights, obligations, and costs.
This article clarifies the five key differences and helps you decide when (or if) to naturalize.
What Is U.S. Lawful Permanent Residency (LPR)?
A Green Card holder is a resident, not a citizen. Residency is revocable under certain conditions.
- Rights: Live/work anywhere in U.S., own property, attend public schools, receive some federal benefits (after 5 years).
- Obligations: File U.S. taxes on worldwide income, register for Selective Service (males 18-25), notify USCIS of address changes.
- Limitations: Cannot vote in federal elections, cannot hold most government jobs (e.g., FBI, State Dept.), cannot petition for parents or siblings (only spouse/unmarried children).
- Travel risk: Absence exceeding 6 months may trigger presumption of abandoning residence. Over 1 year without a reentry permit voids Green Card.
Critical fact: Residents can be deported for certain crimes (aggravated felonies, fraud, domestic violence). Citizens cannot be deported.
What Is U.S. Citizenship?
Citizenship is permanent, unconditional membership in the national community. Acquired by birth (jus soli) or naturalization.
- Exclusive rights: Vote in all elections, hold a U.S. passport (visa-free travel to 180+ countries), run for public office (except President if naturalized), serve on federal juries.
- Benefits for family: Citizens can petition for parents, married children, and siblings (no wait times for immediate relatives).
- Tax obligations: Still owe U.S. taxes globally, but citizens also have FBAR and FATCA reporting above $10k in foreign accounts.
- Renunciation: Possible but complex (fee of $2,350 + exit tax).
Comparison Table (Key Differences)
- Voting: Resident = No; Citizen = Yes.
- Deportation risk: Resident = Yes (for crimes/abandonment); Citizen = No.
- Travel document: Resident = Reentry permit/Green Card; Citizen = U.S. passport.
- Government jobs: Resident = Limited; Citizen = Most (including security clearance).
- Petition for siblings: Resident = No; Citizen = Yes (F4 category, ~15-year wait).
- Loss after long absence: Resident = Automatic after 1 year; Citizen = Never.
How to Go from Residency to Citizenship (Naturalization)
Eligibility requirements (most common):
- Continuous residence for 5 years (or 3 years if married to a U.S. citizen).
- Physical presence in U.S. for at least half of that time (30 months out of 5 years).
- Good moral character (no certain criminal record).
- Pass English and civics test (100 questions; need 6/10 correct).
- File Form N-400 ($710 total fee).
Pro tip: If you never plan to vote or get a passport, residency may be sufficient. But for security and family reunification, citizenship is vastly superior.
Finally, note that dual citizenship is allowed (U.S. does not require renouncing your original citizenship, though your home country may).
