What Is Naturalization?
Naturalization is the legal process through which a non-U.S. citizen voluntarily becomes a U.S. citizen. To qualify, you must meet specific requirements set by law and prove that you are of good moral character, possess basic English skills, and have a solid understanding of U.S. history and government.
Eligibility Requirements
Before you apply, ensure you meet these basic criteria:
- Age: You must be at least 18 years old.
- Permanent Residency Duration: Generally, you need to have been a lawful permanent resident for at least 5 years—or 3 years if married to a U.S. citizen.
- Physical Presence: You must have physically lived in the U.S. for at least 30 months (2.5 years) out of the 5-year period (or 18 months if married to a U.S. citizen).
- Residency: You must have resided continuously in the USCIS district or state where you intend to apply for at least 3 months.
- Good Moral Character: You must demonstrate that you have maintained good moral character during the statutory period.

After the interview, USCIS will send you a notice with one of the following outcomes:
- Granted: Your application is approved.
- Continued: More evidence or a second interview is required.
- Denied: Your application is rejected (you may appeal or reapply after addressing the issues).
