Wondering how to become a U.S. citizen can feel overwhelming, especially with all the forms, rules, and requirements involved.
Here’s something that helps: the process follows a clear path once you understand where you stand.
Whether you already hold a green card or you are just starting to explore your options, knowing what to expect can make the journey much less stressful.
This blog breaks down eligibility, requirements, and the exact steps involved, so you can move forward with confidence and avoid common mistakes along the way.
Who Can Become a U.S. Citizen?
There are three ways to become a U.S. citizen:
- Birth in the United States. Anyone born on U.S. soil is automatically a citizen, no matter where their parents are from.
- Birth abroad to U.S. citizen parents. Children born outside the U.S. can still be citizens if at least one parent was a citizen at the time of birth.
- Naturalization. This is the legal process that allows lawful permanent residents, also called green card holders, to become full U.S. citizens.
If you’re a green card holder wondering when and how you can apply, you’re in the right place. Here’s what it actually takes to naturalize.
Citizenship Requirements for Naturalization
To qualify for naturalization, applicants must meet USCIS residency, character, and knowledge requirements.
Residency and Physical Presence Requirements
You’ll need a green card for at least five years, or three years if married to a U.S. citizen. You also need to physically live in the U.S. for at least half that time.
You must also have lived in the state or USCIS district where you are applying for at least three months before filing.
Short trips outside the U.S. are usually fine, but staying away too long can reset your eligibility clock.
Good Moral Character, English, and Civics Requirements
Applicants must demonstrate good moral character during the required statutory period.
Criminal conduct, immigration violations, tax problems, fraud, false testimony, or other conduct may affect eligibility, depending on the circumstances.
A well-written letter of recommendation for immigration can help support this part of your case.
You also need basic English skills, including reading, writing, and speaking. The civics test requires knowledge of U.S. history and government.
Starting October 20, 2025, USCIS began using an updated civics test with 128 possible questions instead of 100, and applicants must now answer 12 out of 20 correctly instead of 6 out of 10.
How to Become a U.S. Citizen: The Naturalization Process Step by Step
Becoming a citizen involves several clear steps, from filing your application to taking the Oath of Allegiance.
- File Form N-400: Submit your naturalization application online or by mail, along with the filing fee and required documents.
- Attend your biometrics appointment: USCIS collects your fingerprints, photo, and signature for background checks.
- Complete the interview: A USCIS officer reviews your application and asks questions to confirm your eligibility, often following a pattern similar to common immigration interview questions asked at other stages of the process.
- Take the English and civics tests: You must show basic English skills and pass the civics test. If you filed after October 20, 2025, you’ll take the updated version instead.
- Receive a decision: USCIS approves, denies, or asks for more evidence based on your interview and test results.
- Attend the oath ceremony: You take the Oath of Allegiance and officially become a U.S. citizen.
Naturalization Cost and Processing Time in 2026
The current Form N-400 naturalization fees remain $710 online and $760 by paper. Qualifying applicants can also pay a reduced $380 paper-filing fee.
The June 2026 DHS proposal would change the fees to:
Filing Method | Current Fee | Proposed Fee |
|---|---|---|
Online Form N-400 | $710 | $1,280 |
Paper Form N-400 | $760 | $1,330 |
Reduced fee | $380 | Would be eliminated |
Note: The $1,330 figure is a proposed paper-filing fee, not a current fee. The proposal would also raise the online filing fee to $1,280 if finalized.
Exceptions to the Standard Requirements
Not everyone follows the standard naturalization path. Some applicants qualify for exceptions based on service, age, health, or family.
- Military service: Current or former U.S. military members may qualify for faster naturalization, sometimes with reduced residency requirements or no fee.
- Age and residency English exemptions: Applicants who are 50 or older with 20 years as a green card holder, or 55 with 15 years, can skip the English test but still must pass civics in their native language.
- Disability waivers: Applicants with a qualifying physical, developmental, or mental impairment may request an exception from the English and/or civics requirements by submitting Form N-648, Medical Certification for Disability Exceptions, completed by a qualified medical professional.
- Children of citizens: Some children may get U.S. citizenship through a citizen parent without the usual naturalization, depending on age, residence, custody, immigration status, and the parent’s citizenship history.
Common Reasons Naturalization Applications Get Denied
USCIS can deny Form N-400 when an applicant fails to meet eligibility, residence, character, testing, or disclosure requirements. Current policies also allow closer review of an applicant’s background.
Reason | Why It Can Cause Denial |
|---|---|
Poor moral character | Criminal, tax, or conduct issues |
False information | Misstatements or hidden records |
Residence problems | Continuous-residence rules not met |
Failed tests | English or civics requirements not passed |
Eligibility issues | Required conditions are not satisfied |
Neighborhood investigation | USCIS may verify residence, employment, character, and other eligibility facts |
Note: The neighborhood-investigation policy was issued on August 22, 2025, not August 2026. It ended the general waiver of these investigations and remains relevant to naturalization reviews in 2026
When to Talk to an Immigration Attorney
Naturalization applications are usually simple enough to handle on your own.
However, some situations are more complicated, such as past criminal issues, prior immigration violations, or a denied application.
An attorney can also help if your case involves special circumstances, like a disability waiver or unclear residency history.
Getting an attorney involved the moment more than one of these applies at once; the combinations are where cases stall.
Getting legal guidance early can help you avoid delays or mistakes that affect your eligibility. If your situation feels complex, it may be worth speaking with an immigration attorney before you file.
Final Thoughts
Becoming a U.S. citizen takes time, patience, and the right preparation, but the path is clear once you know the steps.
Meeting residency rules and passing the required tests bring you closer to U.S. citizenship.
If you think you may qualify for an exception, like military service or an age-based waiver, it’s worth looking at those options early.
