Part of our Immigration Law FAQ. This cluster covers who is eligible to naturalize and the residence, presence, and character requirements that most often trip up an otherwise-qualified applicant. For our detailed post on the current civics test, see USCIS Announces New 2025 Naturalization Civics Test.
Who is eligible to apply for naturalization?
The general rule (INA § 316(a)) requires five years as a lawful permanent resident immediately before filing, continuous residence and physical presence in the U.S. during that period, good moral character, and passing the English and civics requirements. Married to a U.S. citizen, and living with that spouse, the required period drops to three years under INA § 319(a). Certain other categories — including some who served in the U.S. military — have their own, shorter or modified requirements.
What is the difference between “continuous residence” and “physical presence”?
Continuous residence means you have not abandoned the United States as your permanent home during the statutory period; physical presence is simpler — it is a running count of the actual days you were physically in the country, and you must have been present for at least half of the required period (INA § 316(a)(1), (b)). You can satisfy physical presence on paper and still have a continuous-residence problem if a long trip abroad looks like you relocated, so both are tracked separately.
Does a trip abroad reset my naturalization clock?
It can. An absence of six months to a year creates a rebuttable presumption that continuous residence was broken (INA § 316(b)); an absence of one year or more generally breaks continuous residence outright, absent an approved reentry permit or an exception (such as certain government or qualifying employment abroad under INA § 317). If you are counting down to your eligibility date, a planned long trip is exactly the kind of thing to check with your attorney before you book it, not after.
What counts against “good moral character” specifically for naturalization?
Naturalization applies the INA § 101(f) good-moral-character bars (see our Green Card Categories FAQ for the general list) over the statutory period immediately before filing — five years, or three for spouses of U.S. citizens — but USCIS is not limited to that window: conduct before the period, including certain serious crimes, can still be considered under 8 C.F.R. § 316.10(a)(2). This is also the area where current USCIS policy exercises the most discretion, so any criminal history — even old, resolved, or seemingly minor — should be reviewed before filing, not disclosed for the first time at the interview.
What does the English and civics test require?
Applicants must generally demonstrate an understanding of English (reading, writing, and speaking) and knowledge of U.S. history and government, tested through the civics exam (INA § 312). USCIS periodically updates the civics test content and format — see our post on the current version for what’s actually tested. Age- and residency-based exemptions from the English requirement (and, for some applicants, the civics requirement) exist under INA § 312(b) for certain older, long-term permanent residents.
Can I naturalize if I have a criminal record?
It depends entirely on the offense and when it occurred. An aggravated felony conviction (INA § 101(a)(43)) after November 29, 1990 is a permanent bar to good moral character — and to naturalization — regardless of how long ago it happened. Other offenses may only bar character during the look-back period, or may not bar it at all, but applying with unresolved criminal history can also trigger removal proceedings rather than just a denial. This is not an area to guess about — a case-specific review before filing is essential.
Next: removal, detention & appeals; inadmissibility & waivers. These FAQs are general information, not legal advice, and do not create an attorney-client relationship.
Do my children automatically become U.S. citizens when I naturalize?
Often, yes. Under the Child Citizenship Act, INA § 320, a child automatically acquires citizenship when three things are true before the child’s 18th birthday: at least one parent is a U.S. citizen (by birth or naturalization), the child is a lawful permanent resident, and the child resides in the United States in that parent’s legal and physical custody. No application is required for the citizenship itself — though a Certificate of Citizenship (Form N-600) or U.S. passport documents it. Children who miss the age-18 cutoff must naturalize on their own.
When can I file my N-400 — is there an early-filing rule?
Yes. INA § 334(a) and 8 C.F.R. § 334.2(b) let you file the N-400 up to 90 days before you complete the required period of continuous residence (five years, or three years for spouses of U.S. citizens under INA § 319(a)). Every other requirement — physical presence, good moral character, residence in your state or USCIS district for three months — must still be satisfied. Filing even one day earlier than the 90-day window allows results in denial, so calculate the date precisely.
Can I naturalize through military service?
Military service creates two special paths. INA § 328 covers one year of honorable service, relaxing the residence requirements. INA § 329 is broader: honorable service during a designated period of hostilities (which includes September 11, 2001 to the present) allows naturalization with no minimum residence or physical-presence period at all, and applications can even be completed abroad. Fees are waived for both. Veterans and service members are also protected from some of the traps that catch civilian applicants — but good moral character is still required.
Can I lose my citizenship after I naturalize?
Denaturalization is rare but real. Under INA § 340 (8 U.S.C. § 1451), the government can revoke naturalization obtained by concealment of a material fact or willful misrepresentation — which is why complete honesty on the N-400 (including about arrests, prior deportations, and even offenses that were never charged) matters so much. Truthful naturalized citizens have the same secure citizenship as the native-born; the risk lives almost entirely in what the application hid.
