1. What is N400 Eligibility?

The N400 form is used to apply for U.S. citizenship through naturalization. One of the key eligibility requirements is having been a permanent resident (green card holder) for at least 5 years (or 3 years if married to a U.S. citizen).

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( PR\ years \) — Number of years as a permanent resident

Explanation: The calculator checks if your permanent resident status meets or exceeds the 5-year requirement for standard naturalization eligibility.

3. Importance of Eligibility Calculation

Details: Determining your eligibility before applying for naturalization can save time and resources by ensuring you meet the basic requirements before beginning the application process.

4. Using the Calculator

Tips: Enter the number of complete years you have held permanent resident status. The calculator will determine if you meet the minimum 5-year requirement.

5. Frequently Asked Questions (FAQ)

Q1: What if I've been a PR for exactly 5 years?
A: You meet the minimum requirement but must also meet all other naturalization requirements.

Q2: Are there exceptions to the 5-year rule?
A: Yes, if married to a U.S. citizen, the requirement is reduced to 3 years of permanent residency.

Q5: Is this calculator official?
