N-400 Filing Fee: Complete Guide to Naturalization Costs

The N-400 filing fee is one of the most common questions people have when they begin the naturalization process. As of April 1, 2024, USCIS charges $760 to file Form N-400, the Application for Naturalization. This fee applies whether you file online or by mail, and it's non-refundable — even if your application is denied, USCIS keeps the filing fee for processing costs.

That $760 figure can feel significant, especially for applicants who've already spent years and thousands of dollars navigating the immigration system. But it's worth understanding exactly what you're paying for, who can pay less or nothing at all, and what happens if you can't afford it. There are legitimate pathways to fee waivers and exemptions that many eligible applicants don't know about — and missing them means paying unnecessarily.

This guide covers the current N-400 filing fee in full detail: how it breaks down, how to pay, who qualifies for a reduced fee or complete waiver, special rules for military members, and common mistakes applicants make when submitting payment. By the end, you'll know exactly what you owe and how to make sure your payment doesn't cause delays or rejections in an already complex process.

It's also worth knowing that USCIS can change its fees again in the future. The agency operates primarily on application fees — not congressional appropriations — so its revenue depends directly on fee volume and fee amounts. When USCIS faces processing backlogs, it typically responds with staffing increases funded partly through fee adjustments. Monitoring USCIS.gov for fee announcements is worthwhile for anyone who hasn't yet submitted their application, particularly if you're waiting to gather documents or save money for the fee before you file. A fee increase between now and your filing date would mean paying more than you budgeted.

One important note before we begin: USCIS fees change periodically, and the April 2024 fee schedule represented a significant revision. Always verify the current fee on USCIS.gov before filing — submitting the wrong amount is one of the most common reasons N-400 applications are rejected for technical deficiency, requiring resubmission and additional delays.

The naturalization process involves more than just the USCIS filing fee, and it's worth understanding the full financial picture before you begin. The $760 government fee is the mandatory cost you pay directly to USCIS. Beyond that, many applicants choose to hire an immigration attorney or accredited representative to review their application — attorney fees for N-400 assistance typically range from $500 to $1,500 depending on complexity and geography, though this is completely optional. If your situation is straightforward — you've been a lawful permanent resident for at least five years, have no criminal history, and meet all standard eligibility requirements — many applicants successfully file on their own without legal assistance.

Another cost consideration that often surprises applicants: if you have a prior visa or immigration status that required attorney assistance, naturalization is generally the simpler part of the process to handle yourself. The N-400 is long — 21 pages — but most questions are factual and straightforward. USCIS also offers free instructional videos and form guides on its website. The $760 fee is fixed whether you file alone or with attorney assistance, but the attorney's additional fees are entirely within your control to minimize or eliminate.

The $760 N-400 filing fee covers the full cost of processing your naturalization application, including the biometrics (fingerprinting) appointment. Prior to April 2024, USCIS charged a separate $85 biometrics fee in addition to the form filing fee — that separate charge has been eliminated, and everything is now bundled into the single $760 fee. For applicants who filed before the fee change, the combined old fee was actually lower: $640 for the N-400 plus $85 biometrics = $725 total. The new unified fee is $35 more but simplifies the payment process.

Some applicants qualify for a reduced fee of $380 — exactly 50% of the standard fee. This reduced fee is available to individuals whose household income is between 150% and 400% of the Federal Poverty Guidelines. To apply for the reduced fee, you must complete and submit Form I-942, Request for Reduced Fee, along with your N-400. USCIS will review your income documentation and either approve the reduced fee or request additional evidence. If approved, you pay $380 instead of $760 and your application proceeds normally.

A complete fee waiver — meaning you pay nothing — is available for applicants whose household income is at or below 150% of the Federal Poverty Guidelines. To request this, you submit Form I-912, Request for Fee Waiver, with your N-400. You can also qualify for a waiver if you receive a means-tested public benefit like Medicaid, SSI, SNAP, or TANF, or if you can demonstrate financial hardship on a case-by-case basis. USCIS adjudicates fee waiver requests separately from the main application.

Military members and veterans who meet specific criteria can file Form N-400 with zero filing fee. This exemption applies to: members of the U.S. armed forces currently serving during hostilities or a designated military operation, veterans who served honorably, and family members of qualifying service members in certain circumstances. Military applicants should check USCIS Military Help resources for their specific eligibility pathway before filing, as the documentation requirements differ from civilian applications.

Income eligibility for the reduced fee and waiver programs is calculated using household income — not just individual income. If you live with others and their income contributes to your household, you'll need to account for their earnings too. The Federal Poverty Guidelines are updated annually by the Department of Health and Human Services, typically in January or February. USCIS uses the most current guidelines when reviewing fee waiver and reduced fee requests, so even if you researched eligibility six months ago, it's worth re-checking whether your household income still falls within the qualifying range under the current year's guidelines.

Non-profit organizations that provide immigration legal services are another resource for applicants who can't afford the filing fee. Many USCIS-recognized non-profit organizations hold naturalization clinics where they help applicants complete Form N-400, assess fee waiver eligibility, and sometimes cover the filing fee through grants or public funding. Search for USCIS-recognized organizations in your area through the Accredited Representatives search tool on USCIS.gov — these organizations are legally authorized to provide immigration assistance at no cost or low cost.

USCIS accepts several payment methods for the N-400 filing fee, and the accepted methods differ depending on whether you file online or by mail. For online filers, USCIS accepts credit cards (Visa, MasterCard, American Express, Discover), debit cards with a Visa or MasterCard logo, and prepaid cards. Bank-to-bank ACH transfers aren't supported for online filings. The online payment system is integrated into the USCIS account platform — when you complete your online N-400, you pay at the final step before submitting.

For paper filers, USCIS accepts personal checks, cashier's checks, money orders, and credit cards via Form G-1450, Authorization for Credit Card Transactions. Make your check or money order payable to "U.S. Department of Homeland Security" — not to "USCIS" and not to "Department of Homeland Security" (slight variation can cause processing issues). Write your A-Number (Alien Registration Number) on the check if you have one. Do not send cash under any circumstances — lost cash cannot be traced or refunded.

Returned or rejected payments are a serious problem. If your check bounces or your credit card is declined, USCIS treats the application as if no payment was made and may reject the filing. You'll also be charged a $30 returned payment fee in addition to any fees from your bank. If USCIS has already begun processing before a payment failure is discovered, the application may be suspended until payment is resolved. The simplest way to avoid this: use a cashier's check or money order for paper filings, as these can't bounce.

Online filing is generally recommended by USCIS and most immigration attorneys, not just for payment simplicity but for several practical advantages. Online filers can check application status in real time through their USCIS account, receive automatic receipt notices instantly, and communicate with USCIS about their case through the online portal. Processing times are often slightly faster for online-filed applications because they bypass the initial manual data entry step that paper applications require. If you have no specific reason to file by mail — such as including physical evidence that can't be uploaded — filing online is the better choice.

Prepaid debit cards are technically accepted for online payment, but they come with a caveat worth knowing: the prepaid card must have a billing address associated with it. Many prepaid cards don't have billing addresses linked to them, which causes payment processing failures. If you're planning to use a prepaid card, verify that it has a registered billing address before your filing session — having your payment fail at the submission step can be frustrating after spending hours completing a long application.

Some applicants wonder whether they can split the filing fee across multiple payment methods. The answer is no — USCIS requires a single payment for the full amount. You can't pay $400 by credit card and $360 by money order, for example. If you're filing by mail, include a single check or money order for the full $760 (or the applicable reduced fee or waiver documentation). If you're filing online, the payment must be made in full through a single payment method at the time of submission.

Understanding what happens after you pay is just as important as understanding the fee itself. Once USCIS receives your N-400 and confirms payment, they send you a receipt notice — officially called a Form I-797 Notice of Action — within a few weeks. This receipt notice contains your 13-digit receipt number, which you use to track your case status online and at USCIS InfoPass appointments. Keep this notice safe; losing it doesn't invalidate your case, but having the receipt number makes everything easier.

The receipt notice does not mean USCIS has approved your application. It simply confirms they've received and accepted your filing. Actual processing — reviewing your application, scheduling the biometrics appointment, and reviewing your background check results — happens after the receipt notice. Current N-400 processing times vary significantly by field office, ranging from 8 months to over 18 months in some locations. You can check estimated processing times by field office on USCIS.gov using your receipt notice date.

One thing many applicants don't realize: the non-refundable nature of the N-400 fee is absolute. If USCIS denies your application, you don't get your $760 back. If you withdraw your application voluntarily, you don't get the fee back. If you make a mistake on the form, get rejected for a fixable error, and have to refile — you pay the full $760 again. This is why getting the application right the first time matters significantly, and why many applicants work with an immigration attorney or accredited representative to review their packet before submission.

For applicants who paid the old fee schedule (pre-April 2024) and are still waiting for adjudication, your payment is valid — USCIS doesn't retroactively charge the difference. The new fee only applies to applications submitted on or after April 1, 2024. If you filed before that date, check your receipt notice date, not today's date, to confirm which fee schedule applies to your case.

If your N-400 is approved and you're scheduled for a naturalization ceremony, that step is also free — there's no additional fee to take the Oath of Allegiance and receive your Certificate of Naturalization. However, replacing a lost or damaged Certificate of Naturalization requires filing Form N-565 and paying a $555 fee, so keep your certificate in a safe place as soon as you receive it. Many new citizens store it with their passport, birth certificate, and other vital documents in a fireproof safe or safety deposit box.

The full timeline from paying the N-400 filing fee to taking the Oath of Allegiance currently averages 12–18 months for most applicants, though this varies widely by USCIS field office location. High-volume offices in major metropolitan areas tend to have longer wait times. Rural or lower-volume offices sometimes process applications in 8–10 months. You can research wait times by office on USCIS.gov and, in some cases, choose to file with a different field office if you're near a boundary. The payment you made begins the clock on this timeline — every reason to get it right the first time.

Something worth knowing about USCIS processing times and your filing date: the date USCIS receives your application matters, not the date you mailed it. This distinction can affect timelines when USCIS is processing cases in order of receipt. If you're filing by mail, use a tracked shipping service so you have proof of when USCIS received your packet, not just when you sent it. For online filers, the receipt timestamp in your account is your official filing date — another clear and notable practical advantage of online submission compared to traditional paper mail. Understanding these mechanics helps you track your place in the processing queue and interpret case status updates accurately as your application moves through the system.
