US Citizenship Test 2026: Civics Questions, Interview Format, and How to Prepare

Quiz US Citizenship Test Practice Questions and Answers

A Complete Guide to the US Citizenship Test

The US citizenship test is the civics portion of the naturalization interview conducted one-on-one by a USCIS officer, alongside an English-language assessment. This guide covers who’s eligible, the step-by-step naturalization procedure, the two parallel civics question pools, fees, retake rules, and how to prepare.

Understanding the US Citizenship Test

For most lawful permanent residents, becoming a US citizen means clearing one specific, well-defined hurdle: the naturalization interview with US Citizenship and Immigration Services (USCIS), which includes the civics test along with an English-language assessment. Unlike many professional licenses, this isn’t a standardized test you take at a testing center — it’s an oral exam administered one-on-one by a USCIS officer as part of your naturalization interview. Knowing exactly how it works, who administers it, and what’s actually being asked takes a lot of the anxiety out of preparing.

Legal basis and administering authority

Naturalization in the United States is governed by the Immigration and Nationality Act (INA), and it is administered by USCIS, a component of the Department of Homeland Security (DHS). USCIS sets the civics questions, the English-language requirements, and the procedures applicants follow from filing through the Oath of Allegiance. Because this is a federal government process tied to immigration law, the requirements and test content are set centrally — they don’t vary by state.

Who is eligible

Broadly, to apply for naturalization you generally need to:

• Be at least 18 years old
• Have held a green card (lawful permanent resident status) for at least 5 years, or 3 years if you are still married to and living with a US citizen spouse
• Meet continuous residence and physical presence requirements in the US
• Have lived for at least three months in the state or USCIS district where you’re filing
• Demonstrate good moral character
• Show a basic knowledge of English and US civics (with some long-standing exceptions, described below)

There are exemptions from the English-language portion — and sometimes from both English and civics — tied to age and length of permanent residency (commonly referred to as the 50/20 and 55/15 rules), as well as accommodations for applicants with certain disabilities. If any of these might apply to you, it’s worth reviewing the specifics with USCIS’s own guidance or an accredited legal representative before you file.

The procedure, step by step

The process typically runs like this: you file Form N-400, Application for Naturalization, either online or by mail. USCIS then schedules you for biometrics (fingerprinting) if required, followed by an in-person interview. At that interview, a USCIS officer reviews your application, tests your English (reading, writing, and speaking), and administers the civics test. If you pass everything and your application is approved, you’re scheduled for an Oath of Allegiance ceremony — the final step that actually makes you a US citizen.

What changed: two different test pools

This is where it’s easy to get confused, because USCIS currently has two civics test versions running in parallel, depending on when you filed:

• Applicants who file Form N-400 on or after October 20, 2025 study from an expanded pool of 128 civics questions. During the interview, the officer asks up to 20 of these questions, and you need to answer at least 12 correctly to pass. The officer stops asking as soon as you’ve clearly passed or failed, so you won’t necessarily be asked all 20.
• Applicants who filed before that date are tested under the previous structure: a 100-question pool, with 10 questions asked and at least 6 correct answers needed to pass.

If you’re not sure which pool applies to you, check your N-400 filing date — it’s the date that determines which list you should actually be studying from. Applicants who are 65 or older and have held a green card for 20 years or more also benefit from a long-standing accommodation that limits their required study list to a shorter, specially marked set of questions.

Fees

As of 2026, the standard USCIS filing fee for Form N-400 is $710 if filed online or $760 if filed by paper. Applicants with limited income may qualify for a reduced fee or a full fee waiver. USCIS has proposed raising naturalization fees substantially, but as of this writing that increase had not been finalized, so it’s worth confirming the current fee on USCIS’s official fee schedule before you file.

Validity and what happens after you pass

US citizenship obtained through naturalization doesn’t expire or need renewal the way a license or certification might — once you take the Oath of Allegiance, your citizenship is permanent (though it can, in rare cases, be revoked through denaturalization proceedings for fraud or certain other serious issues). If you ever lose your Certificate of Naturalization, USCIS has a separate replacement process.

If you don’t pass on the first try

Failing isn’t necessarily the end of the road. If you fail either the English test or the civics test (or both) at your first interview, USCIS will reschedule you for a second interview, typically 60 to 90 days later, to retest only the portion(s) you didn’t pass — you won’t have to repeat a section you already passed. If you fail the same portion again at that second interview, USCIS can deny your application, though you generally retain the option to file a new N-400 later or, in some circumstances, request a review of the decision.

How to actually prepare

The most effective preparation mirrors the real interview as closely as possible:

1. Study the correct list. Confirm whether you fall under the 2025 (128-question) or earlier (100-question) pool before you start memorizing anything.
2. Practice out loud, under time pressure. The civics test is spoken, not written, and questions come in random order — reading answers silently doesn’t build the same recall.
3. Mix in English practice. Since reading, writing, and speaking are all assessed, practicing plain English sentences related to civics content does double duty.
4. Use realistic, randomized practice questions that pull from the full pool rather than always reviewing the same ordered list — this better simulates how an officer will actually question you and helps surface the specific items you keep getting wrong.
5. Review official USCIS study materials alongside your practice sessions, since the exact wording of the approved answers matters.

Treat the lead-up to your interview the way you would any oral exam: steady, repeated practice with realistic conditions beats last-minute cramming, and knowing exactly which rules apply to your filing date means you walk in studying the right material from day one.
