Whether you’re applying online or by mail, the Form N-400 (Application for Naturalization) comes with filing and biometric fees that vary based on your circumstances. Add to that optional costs — like legal help, document preparation, or test materials — and the total expense can surprise many applicants.
In this complete 2026 guide, we’ll break down every cost associated with applying for U.S. citizenship, from the base USCIS filing fee to biometrics, fee waivers, and optional legal expenses. You’ll also learn what’s changing under the new USCIS fee schedule, who qualifies for reduced costs, and how to pay your fees safely and correctly.
If you’re planning to apply for citizenship in 2026, this guide will help you budget smartly, avoid unexpected fees, and prepare with confidence for one of the most important steps in your immigration journey.
The Form N-400, or Application for Naturalization, is the primary form used to apply for U.S. citizenship. As of 2026, the USCIS filing fee remains the largest part of the total cost — and it has seen steady adjustments over recent years to reflect administrative processing expenses.
According to the latest USCIS fee schedule updates, the base filing fee for Form N-400 in 2026 is expected to be around $760 for paper filing and $710 for online filing. This reflects a modest increase from the 2025 rate (approximately $725 for both versions). The higher paper-based fee encourages applicants to use USCIS’s digital system, which streamlines document submission and processing times.
The filing fee supports the review of your naturalization application, including:
It’s important to note that USCIS fees are non-refundable, even if your application is denied. That’s why preparing thoroughly — and submitting a complete, accurate N-400 form — is essential before paying.
If the filing cost seems high, you may qualify for a fee waiver (Form I-912) or a reduced fee (Form I-942).
If approved, the reduced N-400 fee for 2026 may be around $380, while full fee waivers cover the entire amount.
Always verify the current fee on the official USCIS Fee Schedule page before filing, as adjustments can take effect midyear. To avoid delays, include the correct fee amount and double-check your payment method before submitting your application.
In the next section, we’ll cover another important part of your citizenship cost — the biometric services fee, and when you’ll need to pay it.
In addition to the Form N-400 filing fee, most applicants must also pay a biometric services fee, which covers the cost of identity verification and background checks through fingerprinting, photographs, and digital signatures.
As of 2026, the biometric services fee remains $85 for most applicants, although USCIS may adjust this rate slightly based on its new fee rule and administrative cost updates. This fee is typically required for applicants between the ages of 14 and 79, and it is paid at the same time as the Form N-400 filing fee.
When you pay online through your USCIS account, the total amount (filing + biometrics) is combined into one transaction — making it easier to track and confirm payment.
Certain applicants may be exempt from paying the biometric fee, including:
If you qualify for a full or partial fee waiver, USCIS will automatically remove or reduce the biometric charge when processing your application.
Once USCIS receives your payment and application, they will schedule your biometrics appointment — typically within 3–8 weeks. You’ll receive an official appointment notice (Form I-797C) with the date, time, and location.
At the appointment, USCIS will collect your fingerprints, take your photo, and verify your identity. This step is essential for conducting FBI background checks before you move on to the interview and civics test stage.
Bring your appointment notice and a valid photo ID (such as a Green Card or passport) to your biometrics appointment. If you need to reschedule, contact USCIS before your appointment date to avoid delays — missing it could postpone your entire citizenship process.
In the next section, we’ll explore optional costs you might need to plan for — including attorney fees, document preparation, and study materials.
Beyond the mandatory filing and biometric fees, applicants should plan for optional costs that can make the citizenship process smoother and more efficient. These aren’t required by USCIS, but they’re often part of preparing a strong and complete naturalization application.
Many applicants choose to work with an immigration attorney or accredited representative to ensure accuracy, address eligibility concerns, or get support for complex cases.
You might need to provide certified translations for documents such as birth certificates, marriage certificates, or court records.
While USCIS offers free study guides and practice tests, some applicants prefer to take citizenship preparation classes to build confidence.
If you’re applying from abroad or need to replace a lost Green Card before applying, you might face added costs:
You don’t have to spend a fortune to prepare well. Many local libraries, nonprofit organizations, and adult education centers offer free or low-cost resources for the civics and English tests. Always explore community programs before paying for private classes.
Next, we’ll look at fee waivers and reductions — a key way to lower your total cost if you meet income or eligibility requirements in 2026.
For many applicants, the cost of applying for U.S. citizenship can feel overwhelming. Thankfully, USCIS offers fee waivers and reductions to make the process more accessible for low-income individuals and families. In 2026, these programs continue to play a vital role in ensuring that financial hardship doesn’t stop eligible residents from becoming citizens.
If you’re unable to afford the Form N-400 filing fee and biometric fee, you may qualify for a full waiver using Form I-912 (Request for Fee Waiver).
You can apply for a fee waiver if:
When approved, your entire USCIS fee is waived — meaning you can apply for citizenship at no cost.
If your income is slightly above the fee waiver limit, you may still qualify for a reduced filing fee. Using Form I-942 (Request for Reduced Fee), USCIS allows eligible applicants with household incomes between 150% and 200% of the Federal Poverty Guidelines to pay a discounted N-400 fee (around $380 in 2026).
This option makes the citizenship process more affordable while maintaining accountability for applicants who can contribute part of the cost.
Certain groups are automatically exempt from paying naturalization fees, including:
💡 Pro Tip: USCIS will deny applications missing financial evidence or incomplete forms. Always review the latest Form I-912 and I-942 instructions on the USCIS website before filing.
Next, we’ll go over how to pay your USCIS fees in 2026, including accepted payment methods and tips to avoid common mistakes.
Once you know the total amount you’ll need to pay, the next step is understanding how to make your payment correctly. USCIS accepts several payment methods in 2026, and choosing the right one can help you avoid delays or rejections.
The easiest and most secure method is to pay through your USCIS online account at my.uscis.gov.
💡 Tip: Always print or save your online payment confirmation. It acts as proof of submission if there’s ever a delay in processing.
If you’re filing a paper application, you can pay using one of the following:
Always include the correct total and double-check your payment type. If your payment fails or the check bounces, USCIS will reject your application.
If you submitted a fee waiver (Form I-912) or reduced fee request (Form I-942), do not include payment unless USCIS denies your request. Once approved, the system will automatically apply the adjusted amount.
After payment, USCIS will issue a receipt number starting with three letters (such as IOE or LIN). You can use this number to track your case online and verify that your payment was processed successfully.
If a payment issue arises, USCIS will send a notice explaining the problem and how to correct it.
In the next section, we’ll review other related expenses — small but important costs that many applicants overlook when budgeting for citizenship.
Even after you’ve paid your USCIS filing and biometric fees, there are a few additional expenses to keep in mind when budgeting for your citizenship application. These costs aren’t officially part of the application fee, but they can affect your total out-of-pocket spending as you move through the process.
Depending on where you live, your biometrics appointment, interview, or naturalization ceremony may take place at a USCIS field office in another city.
If you’re filing by mail, you may need to send your documents using certified or priority mail to track delivery and ensure USCIS receives everything safely.
If your Green Card is expired, lost, or damaged, you must replace it before applying for citizenship.
While the ceremony itself is free, there may be small optional costs, such as:
Citizenship processing can take several months. It’s smart to keep a small financial buffer for rescheduled appointments, updated photos, or reissued documents. A reserve of $100–$200 is often enough for these incidental expenses.
💡 Pro Tip: Plan your citizenship budget as if you’re preparing for a major life event — because you are. By setting aside funds early, you’ll ensure that no step in your naturalization journey catches you off guard.
Next, we’ll cover what to expect after paying your fees — including the processing timeline and USCIS’s refund policies.
Once you’ve submitted your Form N-400 and paid the required fees, the naturalization process officially begins. Understanding what happens next — and what to expect from USCIS — can help you stay organized and avoid unnecessary worry.
After your payment is processed, USCIS will send a Receipt Notice (Form I-797C) confirming that your application has been received.
Within 3–8 weeks, you’ll receive a biometrics appointment notice
If you’ve already submitted biometrics for another application recently, USCIS may reuse them, saving you time.
After biometrics, you’ll wait several months for your citizenship interview and civics test
In 2026, the average processing time for naturalization applications ranges from
8 to 12 months, depending on your local USCIS field office.
During this interview, an officer will review your N-400, test your English and civics knowledge, and confirm your eligibility for citizenship.
If your application is approved, USCIS will schedule you for the Oath of Allegiance ceremony, often within 1–3 months
Once you take the oath, you officially become a
U.S. citizen — and you can apply for your U.S. passport immediately after.
USCIS fees are non-refundable
However, if your application is rejected before processing (for example, due to incorrect payment amount or unsigned forms), USCIS will typically
return your entire package and unprocessed payment.
💡 Pro Tip: Double-check your eligibility, fee amount, and documentation before submitting your N-400. A few minutes of review can save months of waiting — and hundreds of dollars in nonrefundable fees.
Next, we’ll conclude with a summary of everything you need to know to plan and budget effectively for your U.S. citizenship application in 2026.
Applying for U.S. citizenship is more than just a legal step — it’s an investment in your future. Understanding the full cost upfront helps you plan wisely, avoid delays, and ensure that your journey to becoming an American citizen goes as smoothly as possible.
In 2026, expect the Form N-400 filing fee to remain the largest expense, with additional costs for biometrics, legal assistance, translations, and documentation depending on your situation. Thankfully, fee waivers and reduced payments remain available to make naturalization accessible for all qualified residents.
Before submitting your application, always check the latest USCIS fee schedule, confirm your eligibility, and gather all required evidence. A few hours of preparation now can save you time, stress, and unnecessary expenses later.
Becoming a U.S. citizen is a milestone worth every effort — and knowing how to manage the financial side of the process ensures that nothing stands between you and your oath of allegiance. 🇺🇸
