A 90 day early filing date calculator is available on the USCIS website for permanent residents ready to apply for naturalization.


If you are a lawful permanent resident waiting to apply for naturalization, the USCIS has a valuable tool for you to use on its website. You may apply 90 calendar days before the completion of your permanent residence requirements. The “90 calendar days” part can be tricky, as it requires counting calendar days and may involve human error.

90 Day Early Filing Date Calculator

Instead, the 90 day early filing date calculator might save you a headache, at the least, should you be eligible to file your Form N-400 early. The tool will also help you calculate your 90 day filing window to ensure your application is timely filed. The agency’s tool is available for free and does not require any registration. Check out the tool here.

Please note you still must meet all other requirements for naturalization, including being a lawful permanent resident for at least five years, or three years if your permanent residency is based upon your marriage to a U.S. citizen, and be applying under sections 316(a) and 319(a) of the Immigration and Nationality Act (INA).
