N400 Citizenship Application Fee 2026: Your Complete Guide to Naturalization

What if I told you that becoming a U.S. citizen might be more accessible than you think, especially when it comes to understanding the costs involved? Many people assume the N-400 naturalization process is shrouded in mystery and hidden fees. But the truth is, with the right information, you can navigate the N400 citizenship application fee 2026 and the entire journey with confidence.

This guide will break down everything you need to know about applying for U.S. citizenship, focusing on the N400 citizenship application fee 2026, eligibility, and what to expect at each step. We're here to make the complex simple, just like explaining it to a friend over coffee.

What is the N-400 Application for Naturalization?

At its core, the Form N-400, Application for Naturalization, is the official document you use to apply to become a U.S. citizen. It's the gateway to enjoying the full rights and responsibilities of citizenship, such as voting, holding public office, and traveling with a U.S. passport. Think of it as your formal request to join the American family.

Who Can Apply for U.S. Citizenship?

This process applies to you if you are a lawful permanent resident (green card holder) and meet specific eligibility requirements. Generally, you may qualify if you:

• Are at least 18 years old.
• Have been a lawful permanent resident for at least 5 years (or 3 years if married to a U.S. citizen).
• Have been physically present in the U.S. for at least half of that time.
• Have resided for at least 3 months in the state or USCIS district where you apply.
• Can demonstrate good moral character.
• Can pass an English language test (reading, writing, and speaking).
• Can pass a civics test on U.S. history and government.
• Are willing to take an Oath of Allegiance to the United States.

There are some exceptions and additional requirements for certain groups, such as military personnel or those married to U.S. citizens. Always check the official USCIS website for the most current and detailed eligibility criteria.

Understanding the N400 Citizenship Application Fee 2026

One of the first questions many applicants have is about the cost. The N400 citizenship application fee 2026 consists of two main components: the application fee and the biometrics fee. As of the most recent information, here's what you can expect:

• N-400 Application Fee (Paper Filing): $760
• N-400 Application Fee (Online Filing): $710

Good news! The biometrics fee is now included in the N-400 application fee, so you won't pay a separate $85 fee for fingerprinting and background checks. This simplifies the N400 citizenship application fee 2026 significantly.

Reduced Fee Option

USCIS offers a reduced fee option for certain applicants. If your documented household income is greater than 150% but not more than 400% of the Federal Poverty Guidelines, you may qualify to pay a reduced fee of $380. This option is currently only available for paper filings. To apply for the reduced fee, Form I-942 is commonly used, along with your N-400 application.

Fee Waivers

For those facing financial hardship, a fee waiver might be available. If your household income is at or below 150% of the Federal Poverty Guidelines, you are receiving a means-tested benefit, or you are experiencing financial hardship that prevents you from paying the fee, you may qualify for a full fee waiver. Form I-912, Request for Fee Waiver, is commonly used. Military members applying for naturalization are generally exempt from paying the N400 citizenship application fee 2026.

Important: USCIS no longer accepts checks or money order **(Update, June 2026: USCIS no longer accepts checks or money orders for paper filings (since 2024). Use Form G-1450 (card) or G-1650 (bank account))**s for paper filings. Form G-1450 (credit card) or Form G-1650 (bank account) is commonly used for paper applications, or you can pay via Pay.gov for online applications. Always check uscis.gov/feecalculator for the most current fee information.

The N-400 Application Process: Step-by-Step

Navigating the naturalization process can feel like a marathon, but breaking it down into manageable steps makes it much clearer.

Step 1: Determine Your Eligibility

Before you even touch a form, confirm you meet all the requirements mentioned above. This is the most crucial first step. If you're unsure, gathering your green card, travel history, and marriage certificate (if applicable) can help you assess your situation.

Step 2: Prepare and File Form N-400

This is where you gather all your personal information, including your addresses, employment history, travel dates, and any criminal history. Applicants commonly answer questions about their good moral character and their willingness to support the U.S. Constitution. You can file Form N-400 online or by mail.

Key Documents Commonly Used:

• Copy of your green card (front and back).
• 2 passport-style photos.
• 5 years of addresses, employment history, and travel history (or 3 years if married to a U.S. citizen).
• Payment form (G-1450 or G-1650 for paper, or Pay.gov for online) for the N400 citizenship application fee 2026.
• If applicable: marriage certificate, divorce decrees, birth certificates of children, selective service registration proof, etc.

Step 3: Attend Your Biometrics Appointment

After USCIS accepts your N-400 application, they will send you an appointment notice for biometrics (fingerprints, photograph, and signature). This appointment is usually at a local Application Support Center (ASC). Remember, the fee for this is included in your N400 citizenship application fee 2026.

Step 4: Attend Your Naturalization Interview

This is a critical step. A USCIS officer will interview you to verify the information on your N-400, test your English language ability (reading, writing, and speaking), and administer the civics test. Be prepared to answer questions about your application, U.S. history, and government. You can practice for the civics test right here on ImmigrationAlly with our Civics Practice Test.

Step 5: Receive a Decision and Attend the Oath Ceremony

If your interview is successful, you'll typically receive a decision notice. Most applicants are scheduled for an Oath of Allegiance ceremony shortly after their interview. This is the final step where you officially become a U.S. citizen! You'll surrender your green card and receive your Certificate of Naturalization. You can learn more about what to expect at the ceremony in our blog post: N-400 Oath Ceremony: What Happens After Citizenship Approval.

N-400 Processing Times: What to Expect

Processing times for the N-400 can vary significantly depending on the USCIS field office and current caseloads. Generally, you can expect the process to take anywhere from 6 to 12 months. However, this is just an estimate. Always check the official USCIS website at uscis.gov/processing-times for the most current estimates for your specific field office.

What Most People Miss About Naturalization

1. The Importance of Continuous Residence and Physical Presence: These aren't the same! Continuous residence refers to maintaining your status as a permanent resident, while physical presence refers to the actual time you've spent within the U.S. Many applicants accidentally break their continuous residence by taking long trips outside the U.S. without proper planning. Our blog post on N-400 Continuous Residence: Meeting Citizenship Requirements provides more detail.
2. Good Moral Character is Broad: It's not just about criminal history. USCIS officers look at your entire conduct during your time as a permanent resident. This includes things like paying taxes, child sup
