Applying for U.S. citizenship is a major milestone, and one of the first steps is determining whether you are eligible to file Form N-400, the Application for Naturalization. Meeting the eligibility requirements before submitting your application can help prevent delays or unnecessary rejections.
Our N400 Eligibility Calculator is designed to help lawful permanent residents estimate whether they may qualify to apply for naturalization. By entering essential information such as your permanent resident date, marital status, residency period, and time spent outside the United States, the calculator provides an estimated eligibility result based on general naturalization requirements.
This tool is intended as an informational resource and does not replace official legal advice or a decision by U.S. immigration authorities.
What Is an N400 Eligibility Calculator?
An N400 Eligibility Calculator helps estimate whether a lawful permanent resident meets the basic requirements to apply for U.S. citizenship through naturalization.
Instead of manually reviewing eligibility rules, the calculator checks the information you enter and provides an estimated result showing whether you may be eligible to file Form N-400.
Required Inputs
The calculator requires the following essential information:
Green Card Issued Date
Enter the date you became a lawful permanent resident.
Filing Basis
Choose the appropriate category:
- 5-Year Permanent Resident Rule
- 3-Year Rule (Married to a U.S. Citizen)
Continuous Residence
Indicate whether you have maintained continuous residence in the United States.
Physical Presence
Enter the total time you have physically been present in the United States during the required eligibility period.
Long Trips Outside the U.S.
Enter information about any extended absences that could affect eligibility.

How the Calculator Works
The calculator evaluates your information against common naturalization eligibility requirements.
It reviews:
- Required permanent resident period
- Continuous residence
- Physical presence
- Filing category
- Long absences
- Basic eligibility conditions
After processing the information, it provides an estimated eligibility result.
Basic Eligibility Rules
Applicants generally must satisfy several conditions before filing Form N-400.
Common requirements include:
- Be at least 18 years old.
- Hold lawful permanent resident status.
- Meet the required residency period.
- Meet physical presence requirements.
- Maintain continuous residence.

Example
Suppose an applicant:

The calculator would likely indicate that the applicant appears eligible to file Form N-400, subject to official review.
