How to Become a Citizen in the United States
What is the process to obtain U.S. citizenship?
The process in which a person not born in the United States voluntarily becomes a U.S. citizen is called naturalization. For foreign-born persons, naturalization is the most common way to become a citizen in the U.S. In order to naturalize, applicants generally must be permanent residents of the United States and meet several other eligibility criteria. Currently, there are an estimated 9.2 million permanent residents who are eligible to naturalize.
In addition to birth in the United States and naturalization, there is one other way to become a citizen of the United States. Certain foreign-born individuals may have to claim to citizenship through their parents. The may automatically become citizens at birth or after birth (but before the age of 18).

Eligibility for Naturalization
What are the requirements?
You must meet certain requirements before you are eligible to apply for naturalization with Form N-400. Generally, you must be a permanent resident who is at least 18 years old. Here is how to become a citizen in the U.S. based on the three most common eligibility categories:
5-Year Permanent Resident
Married to a U.S. Citizen
U.S. Armed Forces
If you are applying based on five years as a permanent resident or based on three years as a permanent resident married to a U.S. citizen, you may file the application up to 90 days before you meet the “continuous residence” requirement. You must meet all the other requirements at the time that you file your application with USCIS.
The vast majority of applicants fall into one of the categories above. However, there are additional eligibility categories. You can check your eligibility by using CitizenPath's service to prepare the N-400 application. You don't have to pay unless you want to finish the application. There is no cost to check your eligibility.

Cost for Naturalization
How much does it cost to become a U.S. citizen?

Did you know the average 35-year old permanent resident will spend another $4,400 in green card renewal fees over a lifetime? Applicants 75 years of age or older are exempt from the biometric fee, and U.S. armed forces applicants don’t have to pay a fee at all!
Become a Citizen at a Reduced Fee
USCIS will grant a fee waiver if you meet certain criteria and are unable to pay the fees. You will likely qualify for the fee waiver if your income is below 150 percent of the federal poverty guidelines. Other factors that may help you qualify include receiving a means-tested benefit or you are experiencing a financial hardship that prevents you from paying the filing fee. Learn more about fee waivers.
You may request a reduced filing fee for the application if your documented annual household income is greater than 150 percent but not more than 200 percent of the federal poverty guidelines at the time you file.

Pay by Credit Card

Naturalization Time Line
How long does it take to become a citizen?
After you file your application, USCIS will mail you an appointment notice for a biometric screening. This is a relatively quick appointment at a USCIS Application Support Center to obtain your photo, fingerprints and signature. USCIS uses the biometric data to conduct a mandatory criminal background check.
Several months later, USCIS will likely require you to attend a naturalization interview. They will notify you of the time, date, and location for an interview. USCIS uses the naturalization interview to confirm the information you provided on the application. It’s also an opportunity for them to see if circumstances have changed that may make you ineligible. Generally, this is a quick interview that only lasts 20 to 30 minutes. Once the USCIS officer approved Form N-400, you'll be invited to an oath ceremony.
