U.S. Citizenship Requirements for Permanent Residents Married to U.S. Citizens

If you’ve recently received your marriage-based green card, congratulations! Receiving a marriage-based green card grants you lawful permanent resident status, which is a crucial step towards naturalization. This milestone is a big step toward building your life in the United States.

But your journey doesn’t have to stop here. The next step is becoming a U.S. citizen through naturalization. Citizenship provides numerous benefits, including the right to vote, access to certain federal jobs, freedom to travel abroad without restrictions, full protection under the constitution, and permanent protection from deportation.

Introduction: Fast-Track Your Citizenship in Just 3 Years

Naturalization is an exciting milestone for individuals married to U.S. citizens.

If you’re a permanent resident married to a U.S. citizen (even if you didn’t get your green card through marriage!), you might be eligible to apply for citizenship after just three years—two years earlier than the typical five-year requirement.

This pathway, detailed in Section 319(a) of the Immigration and Nationality Act, provides a faster route to naturalization, provided you meet certain eligibility requirements, including the continuous residence requirement.

This guide simplifies the requirements and step-by-step processes for spouses seeking U.S. citizenship, offering fresh insights, useful resources, and clear steps to follow to make your journey to US citizenship as smooth as possible.

Why Apply for U.S. Citizenship?

Becoming a U.S. citizen offers life-changing opportunities and privileges that go beyond permanent residency. Here are some key reasons to consider applying:

Protection from Deportation: Citizenship ensures you can live permanently in the U.S., regardless of legal or policy changes.
Voting Rights: Citizens can vote in federal, state, and local elections, giving you a voice in shaping the nation’s future.
International Travel Freedom: A U.S. passport allows visa-free or visa-on-arrival travel to over 180 countries.
Federal Benefits: Access to government programs like federal financial aid for education and social security benefits.
Family Sponsorship: Citizens can sponsor family members for green cards more easily and quickly.
Job Opportunities: Citizenship opens doors to federal employment and positions that require security clearances.
End the obligation to renew your green card and continuing to pay USCIS filing fees and having to deal with this inefficient bureaucracy.

Data Insights: The Impact of Naturalization

Recent data indicates that over 800,000 individuals become U.S. citizens each year, with marriage-based applicants representing a significant portion of these new citizens.

Naturalization Trends (2015–2025)

In 2024 alone, approximately 150,000 green card holders obtained citizenship through marriage.

Eligibility Requirements: Are You Qualified?

To apply for naturalization through marriage, you must meet the following requirements:

1. Age Requirement

You must be 18 years or older when filing Form N-400.
Selective Service Registration: Male applicants between ages 18 and 26 must register for Selective Service.

2. Marital and Citizenship Status

You must have been married to a U.S. citizen for at least three years.
Your spouse must have been a U.S. citizen for the entire duration of these three years.

3. Residency Requirements

You must have had a green card (permanent resident status) for at least three years.
You must have lived continuously in the U.S. for three years immediately before applying. Breaks in continuous residency can affect the timeline for applying for citizenship and maintaining lawful permanent resident status.
You must have spent at least 18 months physically present in the U.S. during these three years.
You must have lived in the state or USCIS district for at least three months before filing. This applies specifically to spouses of U.S. citizens who are lawful permanent residents.

You must pass tests on English language proficiency (reading, writing, and speaking).
You must demonstrate knowledge of U.S. history and government.
Constitutional Principles: Show attachment to the principles of the U.S. Constitution.

5. Good Moral Character

You must demonstrate good moral character for the three years preceding your application, which involves adhering to U.S. laws, fulfilling tax obligations, and refraining from significant legal offenses or immigration violations.

If Married to US Citizen, You Don’t Need a Marriage-Based Green Card to Qualify for 3 Rule

Important Note: You don’t need a marriage-based green card to qualify for the three year rule. As long as you meet the above requirements, you’re eligible.

Example Scenario:

Maria obtained her green card through her employer.
She married John, a U.S. citizen, and they’ve lived together for three years.

Maria can apply for naturalization

Special Considerations:

Divorce: If you divorce before completing the three-year period, you’ll need to wait until you’ve had your green card for five years.
Criminal Record: Certain crimes can prevent you from becoming a citizen. Consult an immigration attorney if you have concerns. It is advisable to seek the assistance of an experienced immigration attorney to navigate these complexities and ensure all legal requirements are met.

Understanding Continuous Residence vs. Physical Presence

These terms can be confusing, but both are critical to your application:

Continuous Residence: You must have lived in the U.S. without extended absences for the past three years. As a lawful permanent resident, maintaining continuous residence is essential for your eligibility.
Trips longer than 6 months may disrupt continuous residence.
Physical Presence: You need to have been physically present in the U.S. for at least 18 months out of those three years.

Helpful Example

If you took a 7-month trip abroad during your 3-year period, your continuous residence might be broken, even if you meet the physical presence requirement.

Tip: Time spent abroad for extended periods may break continuous residence.

Check out USCIS Tool on calculating physicial presence.

Understanding the Marital Union Requirement

Living in marital union for 3 years means cohabitating with your U.S. citizen spouse for the entire 3-year period before applying.

Exceptions:

If the applicant experiences battery or extreme cruelty by their spouse, the marital union requirement is waived.
If living separately temporarily due to work or school obligation (but still documenting that there is a viable, active marital relationship)

Insight: USCIS requires only a legally valid marriage from the application date until the oath ceremony.

More Information: USCIS Policy Manual – Marriage and Marital Union

90-Day Early Filing Provision

Applicants can file their Form N-400 90 days before completing the required 3-year continuous residence period.

Calculation Example:

If you meet the 3-year residence requirement on June 10, 2025, you can file as early as March 12, 2025.

USCIS Calculator

Special Provisions for Victims of Abuse

Victims of battery or extreme cruelty by their U.S. citizen spouse may still qualify even without fulfilling certain requirements.

Eligibility:

Must have obtained LPR status via an approved self-petition or special rule cancellation.
Waiver available for the marital union and citizen spouse presence requirements.
