Naturalization Application Process: Becoming a U.S. Citizen

For many immigrants, becoming a U.S. citizen is the final step in a long journey—one that started years ago with a visa, green card, or asylum approval. It’s more than just a new passport or the ability to vote. For a lot of people we’ve worked with, it’s about finally feeling like you belong, like the country you’ve built a life in is now officially yours. 

At Tourzani & Long, LLC, we’ve helped clients from all backgrounds apply for naturalization. Some were nervous about the test, others unsure if they qualified. But once the process starts, it’s often smoother than expected—especially if you prepare the right way. Here’s what you need to know if you’re thinking about applying for U.S. citizenship. 

Who Can Apply for Naturalization?

To be eligible, you need to meet a few key requirements: 

• Be at least 18 years old 

• Be a lawful permanent resident (green card holder) for at least 5 years (or 3 years if married to a U.S. citizen) 

• Have lived in the U.S. continuously for that time, with no long absences 

• Show you’ve been physically present in the U.S. for at least half of that time 

• Have lived in your current state or USCIS district for at least 3 months before applying 

• Show good moral character 

• Be able to read, write, and speak basic English (with some exceptions) 

• Pass a U.S. history and civics test 

It’s also important that you haven’t abandoned your residence by spending too much time outside the U.S., and that you’ve filed your taxes properly. Even minor issues—like late filings or unexplained travel—can complicate your application. 

Step 1: File Form N-400

The naturalization process starts with Form N-400, Application for Naturalization. You can file it online or by mail, but either way, you’ll need to include: 

• A copy of your green card (front and back) 

• Payment of the filing fee (or a request for a fee waiver, if eligible) 

• Any documents related to past arrests, divorces, name changes, or military service 

• Your full immigration and travel history 

Accuracy really matters here. Even small inconsistencies—like dates that don’t match your green card or passport—can trigger delays or additional questions from USCIS. 

Step 2: Biometrics Appointment

After you file, USCIS will schedule a biometrics appointment where they take your fingerprints, photo, and signature. This is standard for background checks and usually happens within a month or two of filing. 

You don’t need to bring much to this appointment—just your appointment notice and a valid photo ID—but you should show up on time and follow all instructions closely. 

Step 3: The Interview and Civics Test

Next comes the naturalization interview, where a USCIS officer will ask you questions about your application and test your knowledge of U.S. history and government. You’ll also be asked to read and write one simple sentence in English. 

The civics test includes up to 10 questions from a list of 100 possible questions, and you must answer at least 6 correctly to pass. USCIS posts the full list of questions online, and there are plenty of study tools available. 

Many people worry about this part, but if you’ve been living in the U.S. for years, you probably already know more than you think. We’ve helped clients study with practice quizzes, flashcards, and mock interviews—it really does help take the pressure off. 

Step 4: Decision and Oath Ceremony

If your interview goes well and there are no additional issues, USCIS will approve your application and schedule you for a naturalization oath ceremony. This is where you officially become a U.S. citizen. 

The ceremony is usually held a few weeks after your interview and can be emotional—in a good way. You’ll turn in your green card, take the Oath of Allegiance, and receive your naturalization certificate, which is your official proof of citizenship. 

Once that’s done, you can apply for a U.S. passport, register to vote, and enjoy all the rights and responsibilities that come with citizenship. 

What If There Are Problems?

Sometimes, USCIS requests more information, reschedules your interview, or denies the application. If that happens, don’t panic. You have the right to respond, appeal, or reapply in most cases. 

We’ve seen denials based on long trips outside the U.S., tax issues, or misunderstandings about eligibility. Often, a closer review reveals a path forward—whether that means filing again with better documentation or requesting a hearing to challenge the decision.
