Naturalization is how a lawful permanent resident becomes a U.S. citizen. It is a federal process built around one form, one interview, and a test — but the eligibility rules, and the civics test itself, changed in 2025. Here is the current picture.
Most applicants must meet all of the following. Confirm the details for your situation on the official USCIS Form N-400 page before you file.
Five years as a permanent resident, or three if you have been married to and living with the same U.S. citizen the entire time.
You must be 18 or older at the time you file Form N-400.
You must have lived in the U.S. continuously. Long trips outside the country can interrupt this — see the warning panel below.
You must have physically been in the U.S. for at least half of the required years (about 30 months of 5, or 18 of 3).
USCIS examines your conduct, criminal history, and honesty. Lying on the N-400 is itself a federal crime.
You must show basic English (reading, writing, speaking) and pass a civics test — with exemptions for some older, long-term residents.
This is the detail most outdated guides get wrong, so read it carefully. USCIS now uses two different tests, and the one that applies to you is decided by the date you file Form N-400:
The officer asks up to 10 questions from a list of 100. You pass by answering 6 correctly.
The officer asks up to 20 questions from a list of 128. You pass by answering 12 correctly.
In short: if you file today, you take the larger 2025 test. Because the test is tied to a federal policy that can change again, always confirm the current version and study list at the official USCIS Citizenship Resource Center before your interview. The English portion (reading one of three sentences, writing one of three, and speaking with the officer) and the available exemptions are unchanged.
Before filing, verify your dates and pull together your trips abroad, tax records, and any court or arrest records. The N-400 asks detailed questions about all of it.
Apply online through your myUSCIS account (recommended) or on paper. Answer every question completely and truthfully — a false answer can lead to denial or worse.
USCIS schedules fingerprints and a photo at a local Application Support Center, used for the background check.
At a USCIS field office, an officer reviews your N-400 with you under oath, then administers the English reading/writing test and the oral civics test. Bring your green card and any documents requested.
USCIS grants, continues (for more evidence or a re-test), or denies the application. Most straightforward cases are granted.
You attend a ceremony, take the Oath, and receive your Certificate of Naturalization. At that moment you are a U.S. citizen and can apply for a U.S. passport.
In 2026, the full process commonly takes somewhere in the range of 8 to 18 months, though times vary widely by field office and case complexity. Government filing fees change, so confirm the current N-400 fee on the USCIS Fee Calculator before filing.
Many people treat naturalization as a routine "next step" after the green card. It is not just a formality. The N-400 puts your entire immigration record back under review, including how you originally obtained your green card and everything you have done since.
If there is anything complicated in your past — a criminal arrest or conviction (even an old or expunged one), a prior misrepresentation on an earlier application, long absences abroad, failure to file taxes or to register for Selective Service, or anything that might raise a "good moral character" or removability question — applying can expose it. In the wrong case, that can lead not only to denial but to removal proceedings. The safe move when your history is anything but clean is to have it reviewed before you file.
Citizenship is one of the few immigration matters with genuinely free official support. Before paying anyone, use these:
Start here: the USCIS Citizenship Resource Center and the DOJ list of recognized organizations.
We are a non-attorney legal document preparation service, not a law firm. For a naturalization case that means clear limits:
What we can do: provide published, factual information like this article, and type or complete Form N-400 exactly as you select and direct, when you are representing yourself.
What we cannot do: assess whether you are eligible, advise you on good moral character or how a past issue will be treated, predict the outcome, or represent you at your interview. Those are the practice of immigration law. If your history includes any of the red flags in the panel above, talk to an immigration attorney or a DOJ-accredited representative before you file anything.
The general rule is five years as a green card holder. The three-year rule applies only if you have been married to, and living with, the same U.S. citizen for the entire three years, and that person has been a citizen the whole time. Most other applicants use the five-year track. (Certain military service members have separate, often shorter, rules.)
Yes. Which test you take depends on when you file Form N-400. People who filed before October 20, 2025 take the 2008 test — up to 10 questions from a list of 100, passing with 6 correct. People who file on or after October 20, 2025 take the 2025 test — up to 20 questions from a list of 128, passing with 12 correct. If you are filing now, plan for the 2025 test, and always confirm the current version and official study list at uscis.gov before your interview.
Usually, yes — basic reading, writing, and speaking. But there are age-and-residence exemptions: if you are 50 or older with 20 years as a green card holder, or 55 or older with 15 years, you may take the civics test in your own language with an interpreter and skip the English test. If you are 65 or older with 20 years, you also study a reduced set of civics questions. Applicants with a qualifying medical disability may seek a waiver using Form N-648.
They can. Naturalization requires both "continuous residence" and "physical presence." A single trip of six months or more can raise a presumption that you broke your continuous residence, and a trip of a year or more generally breaks it outright unless you took specific steps in advance. Track your travel dates carefully — officers check them against your record at the interview.
Yes, and many people miss it. Depending on household income, you may qualify for a reduced fee using Form I-942 or a full fee waiver using Form I-912. Eligible military applicants may pay no fee at all. Because fee amounts and thresholds change, confirm the current rules and use the official USCIS Fee Calculator before filing.
For most people with a clean record, no — it is the natural next step. But the N-400 reopens your entire immigration history. If there was a problem in how you got your green card, an undisclosed criminal issue, a prior misrepresentation, or extended absences, applying can surface it and, in serious cases, lead to removal proceedings rather than citizenship. If any of that may apply to you, get a professional review before filing.
In 2026, the process commonly runs about 8 to 18 months, varying by field office and case. A lawyer is not required, and many straightforward cases succeed without one — using free USCIS study materials. But if your case has any complication, an immigration attorney or a DOJ-accredited representative is worth it. Their review costs far less than the risk of a denial or worse.
