What Are the Eligibility Requirements for U.S. Citizenship?
For many immigrants living in New York, U.S. citizenship is a major life goal. It brings the right to vote, a U.S. passport, and a permanent, secure status. However, before you can apply, you must meet specific requirements.
Lawful Permanent Resident Status
To begin, you must hold a green card (lawful permanent resident status) before you can apply for citizenship through naturalization. The standard requirement is that you have held your green card for at least five years. However, if you are married to a U.S. citizen, that window shortens to three years, provided you have been living in marital union with your spouse throughout that period.
Continuous Residence and Physical Presence
In addition to permanent resident status, you must also show that you have continuously resided in the United States for the required period and that you have been physically present here for at least 30 months out of the five years before you file. For those applying based on marriage to a U.S. citizen, the physical presence requirement is 18 months out of three years.
Therefore, it is important to consider how your travel history may affect eligibility. Extended trips outside the United States can create problems. Trips of six months or longer may disrupt your continuous residence. If you travel often or have spent long periods abroad, speak with an immigration attorney before you apply.
State Residency Requirement
Beyond national requirements, you must also have lived in the state or USCIS district where you plan to apply for at least three months immediately before filing. For applicants in New York, this generally means establishing residence in the state before submitting your Form N-400.
Age Requirement
Next, remember that you must be at least 18 years old to apply for naturalization on your own. Children may be able to acquire citizenship through a parent in certain circumstances, but the standard naturalization process requires adult applicants.
Good Moral Character
In addition to age, USCIS requires you to show good moral character for the statutory period, which is usually five years before your application. Some criminal convictions can permanently bar you from naturalization or bar you for a set period. Other conduct, such as failing to pay taxes, failing to pay child support, or committing immigration violations, may also affect eligibility. Every case is reviewed individually.
English Language and Civics Requirements
You will also need to meet English language and civics requirements. Most applicants must show they can read, write, and speak basic English. They must also pass a civics test on U.S. history and government. USCIS updated the civics test in October 2025. The test you take depends on when you file your application.
There are, however, exceptions to the English language requirement for certain older applicants who have held a green card for a long time. For example, applicants who are 50 years or older and have been lawful permanent residents for at least 20 years, or those who are 55 and have held their green card for at least 15 years, may be exempt from the English requirement and can take the civics test in their native language.
Oath of Allegiance
As the final step, you must take the Oath of Allegiance to the United States, affirming your loyalty to the country and its Constitution. This is the last stage in the naturalization ceremony.
