What happens if I failed to file taxes or owe back taxes?

Owing back taxes does not automatically disqualify you from naturalization, provided you have established an approved IRS payment plan and made timely payments. An attorney can help present proof of good moral character.

Citizenship and naturalization

Form N-400 naturalization, civics and English tests, and citizenship acquisition

Naturalization is the process by which a lawful permanent resident becomes a U.S. citizen. Eligibility generally turns on how long you have held your green card, your continuous residence and physical presence, good moral character, and knowledge of English and civics. Our attorneys confirm your eligibility, prepare your N-400, and coach you for a confident interview.

Key areas of citizenship & naturalization

Essential classifications, statutory standards, and relief avenues covered in this guide.

Complete eligibility evaluation and filing of Form N-400.

English & Civics Prep

Test coaching, question reviews, and disability exemption waivers (N-648).

Naturalization Eligibility Requirements

The 5-year and 3-year rules, continuous residence, and physical presence

Most lawful permanent residents are eligible to apply for naturalization after maintaining continuous permanent resident status for at least 5 years. Spouses of U.S. citizens who have been married and living together in a bona fide union for at least 3 years can apply under an expedited 3-year timeline.

Applicants must also demonstrate physical presence in the U.S. for at least 30 months out of the 5-year period (or 18 months out of 3 years), maintain residence in the state or district of filing for at least 3 months, and establish continuous residence without trips abroad exceeding 6 months.

The Naturalization Test and Good Moral Character

The English language exam, 100-question civics test, and statutory character evaluations

During the naturalization interview, applicants must demonstrate basic English reading, writing, and speaking ability, and correctly answer up to 6 of 10 selected questions from the 100-question civics exam. Age and residency exemptions (50/20, 55/15, and 65/20 rules) or medical disability waivers (Form N-648) are available for qualifying applicants.

USCIS strictly evaluates good moral character during the statutory period. Past tax non-filing, failure to pay child support, selective service non-registration, or criminal offenses can jeopardize citizenship eligibility.
