Can I file my N-400 early?

Yes. You can file up to 90 calendar days before you complete your required 5 or 3 years as a permanent resident.

What happens if I file too early?

USCIS will reject an N-400 filed before your 90-day window opens, and you will have to refile. Use your exact earliest date to avoid a rejection and a delay.
