Form N-400, Application for Naturalization

Who Can File N-400 Form for Citizenship?

You need to meet certain eligibility requirements before filing form N 400. You should be 18 years or older and a permanent resident (Green Card holder) now and during all of the past 5 years.

You must reside in the United States for a continuous period before filing the naturalization application. If you are not married to an American citizen, you should reside in the U.S. for a continuous period of five years after admission to the U.S. as a permanent resident. If you are married to a U.S. citizen, you must reside in the U.S. for a continuous period of three years following admission to the U.S. as a permanent resident.

A prolonged absence from the U.S. will break the continuity of your residence in the U.S. for naturalization purposes.
