This article is educational, based on USCIS public materials. MBO Immigration LLC prepares N-400 packets but is not a law firm. If your case includes prior arrests, prior immigration issues, long absences from the U.S., or selective service questions, consult a licensed immigration attorney.

The Form N-400 is the application for U.S. naturalization. After USCIS receives the packet, runs background checks, and schedules biometrics, the case usually leads to one big appointment: the naturalization interview with the civics and English tests.

This article walks you through what happens at that appointment in 2026 and how to prepare.

What happens at the interview

A USCIS officer:

Verifies your identity and reviews the answers in your N-400.
Goes through your background, residence, employment, taxes, travel history.
Tests your English speaking, reading, and writing.
Tests your U.S. civics knowledge.
Asks you to swear to your N-400 truthfulness.
Decides whether to recommend approval, continuation for more evidence, or denial.

The whole interview typically lasts 20–45 minutes.

The civics test

For most applicants in 2026, USCIS uses the 2008 version of the civics test (100 official questions). The officer asks up to 10 questions orally; you must answer at least 6 correctly.

Some applicants — especially anyone enrolled under specific later test versions per USCIS policy memos — may be given a different format. Always confirm on the USCIS Citizenship Resource Center which test applies to you based on your filing date.

The full 100 questions, sample answers, audio, and flashcards are free at the USCIS site.

The English test

Three parts:

Speaking: judged informally throughout the interview.
Reading: read one of three sentences aloud correctly.
Writing: write one of three sentences USCIS dictates.

The vocabulary is intentionally limited. The free USCIS Reading and Writing Vocabulary Lists show every word that may appear.

Exemptions and accommodations

Some applicants qualify for special consideration:

65/20 rule: 65 years or older + 20 years as an LPR → take a shorter civics test (20 questions, must answer 6) in your native language.
50/20 or 55/15: 50+ with 20 years LPR or 55+ with 15 years LPR → exempt from the English part (still take civics, in your language).
Medical exception (Form N-648): applicants with diagnosed conditions that prevent them from learning English or civics.
Disability accommodations: extra time, sign language interpreter, in-person sign language exam, etc.

These are documented in your N-400 (or with N-648 attached) and confirmed at the interview.

How to prepare

USCIS provides everything for free:

Civics test 100 questions (PDF, MP3, online flashcards).
Reading and Writing vocabulary lists.
Practice tests with the same audio that the officer will use.

Most prepared applicants spend 1–4 weeks of consistent study (15–30 minutes/day) and pass on the first attempt. Public libraries and many community organizations also offer free citizenship classes — Google “free citizenship classes near me” or check USCIS Find Help in Your Community.

The interview package — what to bring

USCIS will tell you in your interview notice. Common items:

The interview notice itself.
Green card and a second photo ID.
Passport(s) for every country you’ve held one in.
Tax records for the past 3–5 years (transcripts work).
Selective Service registration evidence if applicable (men 18–25 living in the U.S. as LPRs).
Court records for any arrest, citation, or charge — even if dismissed.
Marriage / divorce certificates for the qualifying period.

Approval, continuation, denial

Three possible outcomes:

Approval recommended: USCIS schedules your oath ceremony, sometimes the same day.
Continuation: officer needs more evidence (often tax docs or selective service proof).
Denial: typically when applicants don’t pass the test twice or miss core eligibility.

You can re-take the test once, scheduled within 60–90 days, before final denial. After that, you re-file.
