After you file Form N-400, the application for naturalization, and complete your biometrics appointment, USCIS invites you to an interview at a local office. For most people this is the single most important day of the whole process. It is also less mysterious than it seems: the interview follows a clear order, and almost everything that happens in it can be practised in advance. This guide walks through it from the moment you arrive.
Before you go
Your interview appointment notice tells you the date, time and place, and which documents to bring. Read it twice. USCIS may ask for documents beyond the usual set, and they are listed on that notice. If you do not bring what it asks for, your case can be delayed. Put everything in one folder the night before: the notice, your Permanent Resident Card, your passports and travel documents, your state ID, and any documents the notice names for your situation.
Plan to arrive early. Federal buildings have security screening, and you will be asked to wait before the officer calls you.
Step 1: The oath to tell the truth
When the officer calls you in, the interview usually begins with you promising to tell the truth. From then on, everything you say is under oath. That is why honest, simple answers matter more than perfect English. If you do not understand a question, it is fine to say so and ask the officer to repeat it or say it another way.
Step 2: Your application, question by question
Most of the interview time is spent on your N-400. The officer goes through your answers to confirm them: your name, addresses, jobs, trips outside the United States, marital history, children, and the long list of yes-or-no questions about your background. Expect questions such as "Have you ever claimed to be a US citizen?" and be ready to explain any "yes" answer you gave on the form.
This part is also your English speaking test. There is no separate speaking exam: the officer judges whether you can understand and answer questions in English during this conversation. The best preparation is to know your own application well. Keep a copy of the N-400 you filed and reread it before the interview, so that your dates and details come to mind easily.
Step 3: The English reading and writing test
Unless you are exempt, the officer asks you to read one sentence aloud and write one sentence down. You have three chances for each: you pass reading by reading one of three sentences correctly, and writing by writing one of three sentences correctly. The sentences use a short vocabulary list that USCIS publishes, built around civics and history words such as names of presidents, holidays and government institutions.
Step 4: The civics test
Then comes the civics test. It is spoken: the officer reads a question and you answer out loud. Which version you take depends on when you filed:
- N-400 filed on or after October 20, 2025: the 2025 test. The officer asks 20 questions from a list of 128. You pass with 12 correct answers, and you fail once 9 answers are wrong.
- N-400 filed before October 20, 2025: the 2008 test. Up to 10 questions from a list of 100, and you pass with 6 correct.
A short answer is enough. If the question asks for one of something, one correct answer is all you need. For questions about your own senators, representative and governor, the answer depends on where you live, so learn yours in advance.
Step 5: The decision
At the end, the officer gives you a written notice of the result. There are three possible outcomes:
- Granted: USCIS can approve your application. In some offices you can even take the Oath of Allegiance at a ceremony on the same day; otherwise you receive a notice for a ceremony later.
- Continued: your case is on hold. The most common reasons are a failed part of the test or missing documents. If USCIS needs more evidence, it tells you what to send and by when.
- Denied: you receive a written explanation of why.
If you do not pass the English or civics test, you get a second chance on the part you failed only, 60 to 90 days after the first interview.
What actually makes people nervous, and what helps
- Hearing the questions from a stranger. Practise with someone reading questions to you aloud, in a neutral voice, without showing you the text.
- Blanking on simple facts. Mixed practice, where questions come in random order, trains you to recall answers without the help of the topic around them.
- Long or unusual words in the N-400 questions. Read through the yes-or-no questions on your copy of the form and look up any word you are unsure of.
- Speaking under pressure. Say your answers out loud every time you practise, even when you are alone. It feels different from reading silently, and the real test is spoken.
A simple checklist for the week before
- Reread your N-400 copy and your appointment notice.
- Check the names that change: President, Vice President, Speaker of the House, Chief Justice, your senators, representative and governor.
- Do two or three full civics runs out loud, in random order.
- Practise reading and writing a few sentences from the vocabulary lists.
- Prepare your document folder and plan your route.
