USCIS Form N-400: Application for U.S. Citizenship

Physical Presence

You must have been physically present in the U.S. for at least 30 months of the last 5 years before applying. If married to a U.S. citizen, you must have been present for at least 18 months of the last 3 years.

Oath of Allegiance

One of the final steps to obtain citizenship is taking the Oath of Allegiance to the United States. By doing so, you pledge to support and defend the Constitution and laws of the country, renouncing allegiance to other nations.

Residency

To qualify for U.S. citizenship, you must have been a permanent resident (Green Card holder) for at least 5 years. If you're married to a U.S. citizen, this period is reduced to 3 years. During this time, you must have continuously lived in the United States.

Good Moral Character

To be eligible, you must demonstrate good moral character. This includes paying taxes, obeying U.S. laws, and not having serious criminal records. USCIS will evaluate your conduct during the required residency period.
