U.S. Citizenship and Naturalization

Naturalization is the process through which lawful permanent residents (green card holders) may become U.S. citizens after meeting specific statutory requirements under the Immigration and Nationality Act (INA). Obtaining U.S. citizenship provides numerous benefits, including the right to vote, apply for a U.S. passport, and petition family members for immigration benefits with fewer restrictions.

Eligibility for Naturalization (Five-Year Rule)

Most applicants qualify for naturalization after maintaining lawful permanent resident status for at least five years. To be eligible, an applicant must:

  • Be at least 18 years old at the time of filing Form N-400;
  • Have been a lawful permanent resident (LPR) for at least five years;
  • Demonstrate continuous residence in the United States during the five years preceding the application;
  • Show physical presence in the United States for at least 30 months within those five years;
  • Have lived for at least three months in the state or USCIS district where the application is filed;
  • Demonstrate good moral character for at least five years before filing;
  • Show attachment to the principles of the U.S. Constitution;
  • Be able to read, write, and speak basic English; and
  • Possess knowledge of U.S. history, civics, and government.

Certain applicants, depending on age and time as a permanent resident, may qualify for exemptions from the English language test and may take the civics test in their preferred language.

Naturalization Through Marriage to a U.S. Citizen (Three-Year Rule)

Applicants who have been living in marital union with a U.S. citizen for at least three years may be eligible to apply sooner. To qualify under section 319(a) of the INA, the applicant must:

  • Have been a lawful permanent resident for at least three years;
  • Have lived in marital union with a U.S. citizen spouse during the three years preceding the application;
  • Demonstrate continuous residence and physical presence in the United States for at least 18 months within those three years;
  • Show good moral character and attachment to U.S. constitutional principles; and
  • Demonstrate basic knowledge of English and U.S. civics.

Continuous Residence Requirement

Applicants must show they have maintained continuous residence in the United States during the statutory period. Continuous residence means maintaining a permanent dwelling or principal place of living in the U.S. Absences of more than six months but less than one year create a presumption of a break in residence, which must be overcome with evidence such as proof of U.S. employment, family ties, or property ownership.

Absences of one year or more automatically break continuous residence unless the applicant has an approved Form N-470, Application to Preserve Residence for Naturalization Purposes. Certain classes, such as U.S. government employees or religious workers, may qualify for special consideration.

Physical Presence Requirement

Applicants must also demonstrate they were physically present in the United States for at least half of the required period—30 months for five-year applicants or 18 months for three-year applicants. Physical presence refers to the actual number of days spent inside the United States, and documentation may include travel records, employment history, or tax filings.

Good Moral Character

Applicants must demonstrate good moral character (GMC) for the statutory period prior to filing and up to the Oath of Allegiance. Conduct such as criminal convictions, failure to pay taxes, or providing false information to immigration authorities can negatively impact an applicant’s GMC assessment. In some cases, earlier conduct may also be reviewed if it reflects on the applicant’s character or honesty.

Testing and Oath Requirements

Applicants must pass an English language test and a civics test unless eligible for an exemption. The civics portion includes questions about U.S. history, government structure, and constitutional principles. After USCIS approval, applicants attend a naturalization ceremony where they take the Oath of Allegiance, completing the process of becoming a U.S. citizen.
