What is Form N-400?

Form N-400 is the application for naturalization: the form a permanent resident uses to ask USCIS to become a United States citizen.

It is one of the longest USCIS forms, and one of the most personal. It asks about your travel, your addresses, your jobs and your history.

The official instructions describe the topics USCIS reviews: time as a resident, physical presence in the country, residence in the state, English and civics, and good moral character.

Each one has exceptions and details written into the instructions. Whether they apply to you is a legal question, and Paso Libre does not answer it: we do not decide your case.

If you have doubts about your history, ask a licensed attorney or a Department of Justice accredited representative before you sign.

The N-400 carries a long section of questions about your history: arrests, taxes, military service, memberships, child support. There are dozens of separate questions.

Each one is answered separately and truthfully. Signing the form is a statement under penalty of perjury, so no answer should be guessed at or lumped in with another.

That is why we ask them one by one, in Spanish, instead of collapsing them into a single box.

USCIS mails a receipt notice, then usually a biometrics appointment, then an interview, and finally an oath ceremony. Each step arrives by mail.

The interview includes an English and civics test, with exceptions USCIS describes on its official page. We do not predict dates or results; USCIS publishes the timelines.

We guide you in Spanish, question by question, and transfer your answers onto the official form with technical checks. You receive an unsigned PDF: you review it, sign it by hand and mail it.

We are not a law firm and we do not give legal advice. If your question needs legal judgment, we tell you where to look for licensed help.

The government fee is paid directly to USCIS and we never mark it up. The general amount is just below, with the date of the official table we read it from; some people pay a different amount.
