1. What is N400 Early Filing?

The N400 Early Filing Calculator determines the earliest date you can submit your Application for Naturalization (Form N-400) based on your Permanent Resident (Green Card) date. USCIS allows filing up to 90 days before meeting the continuous residence requirement.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Early\ Date = PR\ Date + 5\ years - 90\ days \]

Where:

PR Date — Your Permanent Resident ("Green Card") approval date
5 years — Standard continuous residence requirement for most applicants
90 days — Maximum early filing period allowed by USCIS

Explanation: The calculation accounts for both the 5-year continuous residence requirement and the 90-day early filing window permitted by USCIS.

3. Importance of Correct Filing Date

Details: Filing too early may result in rejection of your application. Filing at the optimal time can help streamline your naturalization process while ensuring you meet all requirements.

4. Using the Calculator

Tips: Enter your exact Permanent Resident date (found on your Green Card) in the format MM/DD/YYYY. The calculator will display your 5-year anniversary date and the earliest acceptable filing date.

5. Frequently Asked Questions (FAQ)

Q1: Is the 90-day rule the same for all applicants?
A: The 90-day early filing period applies to most applicants filing under the 5-year rule. Different rules may apply for spouses of U.S. citizens or other special categories.

Q2: What if my PR date was more than 5 years ago?
A: You may file immediately, as you've already met the continuous residence requirement. The calculator will show this by displaying an early filing date in the past.

Q3: Does this account for leap years?
A: Yes, the calculator properly accounts for leap years in its date calculations.

Q4: What time zone does USCIS use for filing dates?
A: USCIS considers the date your application is received at their lockbox facility, based on the facility's local time zone.

Q5: Can I file earlier than 90 days in special circumstances?
A: Generally no, unless you qualify for military service exceptions or other very specific situations. Consult an immigration attorney if you believe you qualify.
