From green card to citizenship: what the N-400 actually asks of you.

The clock that lets you file

Five years, or three if you're married to a citizen

The general path is built on a single number: you must have been a lawful permanent resident for five years of continuous residence before you file Form N-400 (8 CFR 316.2; INA 316). There is a narrower three-year path. If you are married to a U.S. citizen and have been living in marital union with that same citizen spouse — who has been a citizen for the full period — you can file after three years as a permanent resident instead of five (INA 319(a)).

A small mercy USCIS builds in: you may file your N-400 up to 90 days before you hit the five-year (or three-year) mark. That early-filing window applies to the residence clock only — every other requirement, including physical presence, is still measured against the real anniversary.

Two tests, two different things

Continuous residence and physical presence are not the same test

These two requirements sound alike and trip up almost everyone. Continuous residence asks whether your home has stayed in the United States without a long break. Physical presence asks a flat arithmetic question: across your five years, were you actually inside the country for at least 30 months — half the time (8 CFR 316.2(a)(4))? On the three-year spouse path, it is 18 months. You can satisfy one and fail the other.

Continuous residence breaks on the length of a single trip, not your total time abroad. A single absence of more than six months but less than a year creates a rebuttable presumption that you broke continuous residence — you can still overcome it with evidence, but the burden is now yours (8 CFR 316.5(c)(1)(i)). A single absence of one year or more breaks continuous residence outright, unless you secured an N-470 to preserve it before you left (8 CFR 316.5(c)(1)(ii)). One more rule that surprises filers: you must have lived in the state or USCIS district where you file for at least three months before filing (8 CFR 316.2(a)(5)).

Five trips of five months each will not break your continuous residence — but they can still leave you short on physical presence, and a pattern of long absences quietly raises the question of where your home really is.

Who you've been

Good moral character and attachment to the Constitution

Across the statutory period — the five or three years up to the moment you take the oath — you must show good moral character (GMC), judged by a "preponderance of the evidence" standard: more likely than not (INA 101(f)). You also have to show attachment to the principles of the Constitution and a favorable disposition toward the United States. These are not exotic hurdles for most applicants, but they are not pure formalities either.

What is moving is how officers weigh GMC. As of June 2026, an August 15, 2025 USCIS policy memorandum directs officers to apply a holistic, totality-of-the-circumstances standard — weighing positive attributes, not just scanning for the absence of disqualifying conduct. In practice that means your full record can be considered, good and bad. Because this is a recently changed and actively evolving standard, read the current Policy Manual language before you rely on any older summary of how GMC is assessed.

The test that depends on your filing date

2025 test or 2008 test? Your N-400 filing date decides

This is the single most misreported part of naturalization right now, so read the condition carefully. Which civics test you take depends on the date you filed Form N-400 — not your interview date, and not your ceremony date.

• N-400 filed on or after October 20, 2025: you take the 2025 civics test. The officer draws 20 questions from a bank of 128, and you must answer 12 correctly to pass. The officer stops once you reach 12 correct — or once you have answered 9 wrong, which is a fail. The 2025 test is a re-implementation of the 2020 version, adopted as part of an executive-order-driven, multi-step overhaul of the naturalization test.
• N-400 filed before October 20, 2025: you take the 2008 civics test. The officer asks up to 10 questions from a bank of 100, and you must answer 6 correctly to pass.

Do not mix the two. The 100-question / 10-asked / 6-to-pass numbers belong only to the 2008 test; the 128 / 20 / 12 numbers belong only to the 2025 test. The naturalization test has been overhauled before — the framework itself is in motion — so check the official "Check for Test Updates" page for any change before you study from a fixed number.

Exemptions for English and age

Who can skip the English test — and the "65/20" break

The naturalization test has two parts: English (reading, writing, speaking) and civics. Long-resident older applicants get statutory relief from the English part. If you are 50 or older and have been a permanent resident for at least 20 years (the "50/20" rule), or 55 or older with at least 15 years as a permanent resident (the "55/15" rule), you are exempt from the English requirement and may take the civics test in your own language with an interpreter (INA 312).

There is also a civics break, the "65/20" special consideration: if you are 65 or older and have been a permanent resident for at least 20 years, you study a smaller, marked subset rather than the full bank. The officer asks 10 questions from a 20-question list, and you must answer 6 correctly to pass. Separately, applicants who cannot meet the English or civics requirement because of a qualifying medical disability may seek an exemption — these accommodations are handled on their own track.

The moment it's real — and a fear to retire

The oath makes you a citizen, and you don't have to give up your other passport

Approval is not citizenship. After USCIS approves your N-400, you are scheduled for a ceremony, and you become a U.S. citizen only when you take the Oath of Allegiance (USCIS Policy Manual, Vol. 12, Pt. J). The oath includes language renouncing prior allegiances as a matter of U.S. law; modified or waived versions are available in specific circumstances (for example, on religious grounds or for certain disabilities).

Now the fear that stops people who don't need to be stopped: becoming a U.S. citizen does not, by itself, force you to surrender your other citizenship. The U.S. Department of State is explicit that U.S. law does not require a person to choose one nationality over another — many people are dual nationals by the ordinary operation of two countries' laws. The oath is a declaration of primary allegiance under U.S. law; whether your other passport survives is decided entirely by that other country's law, not by anything USCIS does. Some countries permit dual citizenship; others do not. Check your country of origin's rules — not a U.S. source — for that half of the answer.

The card, and the money

An expired card doesn't bar you — and what the N-400 costs

A green card is documentation of your status, not the status itself. Your lawful permanent residence does not expire on the day the plastic does. An LPR whose physical card has lapsed is still a permanent resident and can still naturalize. In fact, when you properly file the N-400, USCIS issues a receipt notice that — as of June 2026, under a policy in place since December 12, 2022 — automatically extends the validity of your green card for 24 months beyond its printed expiration, so you can prove status while you wait. That figure has been adjusted before; confirm the current extension length on the live N-400 page before you rely on it.

On cost: the N-400 fee is rolling-numeric, so treat any dollar figure as a snapshot and re-check it. As of June 2026, against the USCIS G-1055 fee schedule (edition 05/29/26), the base fee runs $760 on paper, with a $50 discount to $710 when you file online; a reduced fee of $380 is available to lower-income applicants who qualify (you must file on paper to claim it); a fee waiver exists for those who meet the income threshold; and there is no fee for qualifying military applicants. Check whether you qualify, and pull the current number from the USCIS Fee Schedule or Fee Calculator before you pay. Processing time, likewise, is field-office specific — never trust a single national number; look up your office on the live USCIS processing-times tool.

What's settled vs moving

What's stable, and what you must re-check before you act

The skeleton here is statutory and steady: the five-year and three-year clocks, the 30-month (or 18-month) physical-presence count, the 3-month state-residence rule, the rebuttable-presumption and one-year continuous-residence mechanics, attachment to the Constitution, and the oath as the moment of citizenship. These rest on the Immigration and Nationality Act and codified regulation that have not moved.

What moves is around the edges. The civics test framework is the loudest example — settled as a rule, but keyed strictly to your filing date and part of a multi-step overhaul that has changed before and could change again, so re-check the USCIS test page. The good-moral-character evaluation standard is policy-manual-driven and fact-specific, so read the current USCIS language rather than relying on an older summary. The fees ($760 / $710 / $380 / $0 here) and the card auto-extension length (24 months) are rolling numbers — pull them live from the G-1055 and the N-400 page. And processing times are office-by-office, never national. Check the official source, and check the date on anything you read.
