📝 Lesson 3.2: The N-400 Application

What Is the N-400?

The N-400 is the Application for Naturalization — the form a lawful permanent resident files with USCIS to request U.S. citizenship. It's the official "step 2" from the process you saw in Lesson 3.1 (check eligibility → file the N-400 → biometrics → interview → tests → decision → Oath).

You can file the N-400 online through a USCIS account, or on paper by mail — both are official options. There is a filing fee, and, as noted in Lesson 3.1, a fee waiver or reduced fee may be available for those who qualify. The current fee, form edition, and filing options are always listed on uscis.gov.

What the Form Asks

The exact questions and their order change between form editions, but the N-400 generally asks about the same areas of your life. Knowing the categories ahead of time removes most of the surprise:

Notice that most of the form is simply your own history: where you've lived, worked, and traveled, and your family. A few questions cover good moral character (like whether you've paid taxes or had legal problems). If any of those apply to you, that is exactly when to consult a licensed attorney before filing — not to hide anything, but to answer correctly and understand your situation.

Documents to Gather

Much of filing is simply collecting the right documents and information ahead of time. Exact requirements depend on your situation and the current instructions, but applicants commonly gather things like:

• Your Permanent Resident Card (green card) information
• A record of your addresses and employment/schools over the required period
• A list of your trips outside the U.S. (dates you left and returned)
• Information about your marital history and children
• Tax information, if asked
• Documents related to any legal issues, if they apply (bring records, don't hide them)
• Information needed for a fee waiver, if you're requesting one

Honest, Accurate, Consistent

If you remember one thing from this lesson, remember this: always tell the truth on the N-400. The application is signed under penalty of law, and honesty is part of the "good moral character" the process looks for.

If something in your history worries you — a past arrest, a tax question, a complicated travel or marriage history — the right move is not to hide it or guess. It's to talk to a licensed immigration attorney or a BIA-recognized accredited representative before you file. They can help you answer truthfully and understand what it means for your case. This is exactly the kind of situation where good, legitimate help is worth it.

Filing & What Comes Next

Once your form is complete and accurate, here's the general flow after you file — so you know what to expect:

    A["Prepare: read instructions, gather documents, fill the N-400"] --> B["File online or by mail, with fee or fee-waiver request"]
    B --> C["Receive a receipt notice (confirms USCIS got it)"]
    C --> D["Biometrics appointment, if required (fingerprints)"]
    D --> E["Interview notice with date, time & place"]
    E --> F["Interview + English & civics tests"]
    F --> G["Decision, then Oath of Allegiance"]

After filing, USCIS sends written notices by mail (and to your online account) — a receipt, then appointment notices. Read every notice carefully, keep them all, and update your address with USCIS if you move, so you never miss one. Missing an appointment can delay your case, so treat every notice as important. The interview and tests are the focus of the next two lessons.
