How is N-400 filled out?

Part by part, in the order USCIS asks — and in our software, from your answers: you answer simple questions once, and the fields fill themselves.

Part by part

What the form asks

  1. Your basis

    The five-year path, or the three-year path for spouses of U.S. citizens.

  2. Residence and travel

    Where you have lived and every trip outside the U.S. — long trips raise continuous-residence questions.

  3. Moral character

    Taxes, arrests, and the yes/no history section. Truthful answers with explanations beat silence.

  4. The tests

    English reading, writing, and speaking, plus the civics test — practiced ahead with the free tool.
