Can I file my N-400 early?

An otherwise qualified applicant may file up to 90 calendar days before completing the applicable five- or three-year permanent-residence period. The allowance does not shorten other requirements, including the spouse-citizenship and marital-union requirements for the three-year path.

What happens if I file too early?

USCIS may reject an N-400 filed before the 90-day window opens. Confirm the calculation and the current instructions before filing.
