When you are eligible to file the N-400
Naturalization has a small number of hard requirements: time as a permanent resident, continuous residence, physical presence, and the tests.
The time requirement
You must generally have been a lawful permanent resident for at least five years, or three years if you are married to and living with the same U.S. citizen for that whole period. You must be at least 18 years old at the time of filing.

Continuous residence and physical presence
You must have resided continuously in the United States for the qualifying period, and have been physically present for at least half of it. A single absence of more than six months can disrupt continuous residence, and an absence of a year or more generally breaks it. You must also have lived for at least three months in the state or USCIS district where you file.
