USA Citizenship by Marriage: The Complete 2026 Guide

Many immigrants believe they must wait five years to become a U.S. citizen. However, under the USA citizenship by marriage provision, you may be eligible to apply for naturalization in just three years.

Navigating the USCIS process requires more than just a marriage certificate; it requires proof of a “marital union” and meeting strict residency requirements. Here is everything you need to know about the fast-track to a U.S. passport.

1. Eligibility: The “3-Year Rule” Explained

To qualify for naturalization through your spouse, you must meet the following criteria as of 2026:

• Age: You must be at least 18 years old.

• Green Card Status: You must have been a Lawful Permanent Resident (LPR) for at least 3 years.

• Marital Status: You must be married to, and living with, the same U.S. citizen spouse for those 3 years.

• Spouse’s Status: Your spouse must have been a U.S. citizen for the entire 3-year period.

• Continuous Residence: You must have lived in the U.S. for at least 3 years and been physically present for at least 18 months.

3. The Naturalization Process Step-by-Step

1. File Form N-400: As of 2026, the standard filing fee is $760 (online filing is recommended for faster processing).

2. Biometrics Appointment: USCIS will take your fingerprints and photo for a background check.

3. The Interview & Test: You will meet with a USCIS officer to review your application. You must pass the English test and the Civics test.

4. Oath of Allegiance: Once approved, you will attend a ceremony to take the Oath and receive your Certificate of Naturalization.

4. Frequently Asked Questions (FAQ)

Can I apply if I am separated from my spouse?

No. To use the 3-year rule, you must be “living in marital union.” If you are legally separated or living apart (unless for valid reasons like military service or work), you may have to wait for the standard 5-year residency period.

What happens if we divorce after I file?

If you divorce after filing the N-400 but before the Oath of Allegiance, you generally lose your eligibility for the 3-year marriage-based path.

How much does it cost in 2026?

The USCIS filing fee for Form N-400 is currently $760. Reduced fees ($380) or full waivers are available for those who meet specific income guidelines.
