N-400 Cost — Filing Fees, Biometrics, and Hidden Expenses

What the N-400 Cost Actually Covers

The N-400 cost isn't one fee—it's two separate government charges, and neither one covers what happens after you file. As of January 2026, USCIS lists the Form N-400 filing fee at $640 and the biometric services fee at $85, for a combined total of $725 when filing online or by mail. That $725 gets your application into the queue and your fingerprints taken. It does not include translations, passport photos, certified documents, or the time and travel you'll spend responding to requests for evidence, attending the biometrics appointment, and appearing for the interview.

The naturalization process costs what it costs because USCIS must verify identity, conduct background checks through FBI databases, review immigration history spanning years or decades, and schedule in-person interviews with trained officers. The fee structure reflects those operational expenses. What it doesn't reflect—and what catches applicants off guard—is the cost of assembling the evidence file that makes approval possible.

This article breaks down the full cost structure: what USCIS charges, what the fee waiver and reduction options cover, and what you'll pay outside the filing fee to complete the process. We'll also compare the current N-400 cost to prior fee schedules and explain what happens if fees change between the time you read this and the time you file.

Current USCIS Filing and Biometrics Fees

USCIS charges two fees for Form N-400:

1. Application filing fee: $640
2. Biometric services fee: $85

Total due at filing: $725 (as of January 2026, per the USCIS fee schedule published at uscis.gov/forms). Payment must accompany the application whether filed online or by mail. Acceptable payment methods include credit card, debit card, check, or money order payable to "U.S. Department of Homeland Security." Personal checks are accepted, but a returned check delays processing and may trigger a rejection notice.

The biometric services fee covers fingerprinting, photograph capture, and signature collection at a USCIS Application Support Center. The appointment is mandatory for most applicants—USCIS uses the biometrics to run FBI and DHS background checks, which form the basis of the security clearance required for naturalization. Applicants age 75 or older at the time of filing are exempt from the biometrics fee, reducing their total cost to $640.

Fee changes occur periodically. USCIS publishes proposed fee rules in the Federal Register, accepts public comment, and implements changes after a final rule is published. The $725 total has been in effect since early 2023. Before filing, confirm the current fee on the USCIS fee schedule page—filing with the wrong amount results in rejection and return of the entire application, resetting your place in the processing queue to zero.

Fee Waiver and Reduction Options

USCIS offers two forms of fee relief for N-400 applicants who meet financial eligibility criteria:

Fee Waiver (Form I-912)

A fee waiver eliminates both the filing fee and the biometrics fee entirely, reducing the N-400 cost to zero. You qualify if your household income is at or below 150% of the Federal Poverty Guidelines, or if you currently receive a means-tested public benefit (Supplemental Security Income, Temporary Assistance for Needy Families, Medicaid, or SNAP). The waiver application requires documentation—pay stubs, tax returns, benefit award letters—proving the claimed income level.

Form I-912 is filed simultaneously with Form N-400. USCIS adjudicates the waiver request first. If denied, you must pay the full fee before the N-400 proceeds to the next stage. If approved, the application moves forward at no cost. The waiver does not cover third-party expenses like document translations, photographs, or postage.

Fee Reduction (Form I-942)

A fee reduction cuts the total N-400 cost to $380 (a $345 discount). You qualify if your household income is between 150% and 200% of the Federal Poverty Guidelines. The reduction is not automatic—it requires filing Form I-942 with the same documentation as a waiver request. The reduced fee is due before USCIS schedules the interview.

Both the waiver and reduction are means-tested, not discretionary. If your income exceeds 200% of the guidelines and you don't receive a qualifying public benefit, you pay the full $725. USCIS does not negotiate, offer payment plans for the filing fee itself, or accept partial payments in installments.

What the Filing Fee Does Not Cover

The $725 USCIS collects gets your application adjudicated, your background cleared, and your interview scheduled. It does not cover:

Document preparation costs:

• Certified translations of foreign-language birth certificates, marriage certificates, or divorce decrees (typically $20–$75 per page, depending on the translator and document complexity)
• Passport-style photographs meeting USCIS specifications (usually $10–$20 at commercial photo services)
• Certified copies of court records, police clearances, or tax transcripts (fees vary by jurisdiction—some courts charge $15–$50 per certified document)

Travel and logistics:

• Transportation to the biometrics appointment (mandatory, not waived even with a fee waiver)
• Transportation to the naturalization interview (also mandatory; rescheduling is permitted but delays the process by months)
• Time off work for both appointments (interviews are scheduled during business hours at USCIS field offices, which may be hours away depending on where you live)

Attorney or accredited representative fees:

• Legal representation is not required for N-400, but many applicants retain counsel, particularly if the application involves prior arrests, extended absences from the U.S., or complex marital history. Attorney fees for naturalization vary widely—some practices charge flat rates between $1,000 and $3,000; others bill hourly. The Law Offices of Peter D. Chu offers a $250 initial consultation to evaluate whether your case requires representation and what that representation would cost.

Replacement documents if the application is denied:

• If USCIS denies your N-400 and you reapply, you pay the full filing fee again. There is no carryover credit from a denied application. A denial also restarts the residency clock if the denial was based on abandonment of permanent residence, so the cost of reapplying includes the cost of resolving the underlying deficiency before refiling.

Budgeting for naturalization means budgeting for the filing fee plus these ancillary expenses. The total cost for a straightforward application with no attorney assistance and minimal document needs typically runs $900–$1,200. Complex cases can exceed $4,000 when legal fees, document retrieval, and multiple trips to the field office are factored in.

Comparison: N-400 Cost Over Time

The N-400 filing fee has increased substantially over the past two decades:

Fee increases typically follow multi-year cycles tied to USCIS budget shortfalls and policy changes published as final rules in the Federal Register. The next proposed rule, if any, will be posted for public comment before it takes effect, giving applicants advance notice to file under the current fee structure if an increase is imminent.

Here's the Honest Answer: The Fee Won't Predict How Long It Takes

Let's be direct: paying $725 does not buy you a faster decision, a guaranteed approval, or any influence over where your application sits in the processing queue. The fee funds USCIS operations—it doesn't prioritize your case over anyone else's. Processing times for Form N-400 vary by field office, current workload, and whether your background check flags anything requiring manual review. As of 2026, posted processing times range from 8 to 18 months depending on location, but individual cases move faster or slower based on factors entirely outside the applicant's control.

What you can control is the completeness of your application and the accuracy of your supporting evidence. An incomplete application triggers a Request for Evidence, adding months to the timeline. A missing document or an unexplained gap in your travel history can delay the interview or result in a denial that forces you to reapply—and pay the fee again. The cost of getting it right the first time is lower than the cost of correcting it after USCIS points out what's missing.

What If I Can't Afford the Fee?

File Form I-912 (fee waiver request) or Form I-942 (fee reduction request) with your N-400. Both forms require financial documentation proving your household income level relative to the Federal Poverty Guidelines. If you qualify, USCIS waives or reduces the fee before proceeding with adjudication.

If your waiver or reduction request is denied, USCIS will issue a notice explaining why and giving you a deadline to pay the full fee. You can appeal the fee decision separately, but the N-400 itself will not move forward until the fee is paid in full. There is no hardship exception beyond the waiver and reduction—USCIS does not offer installment plans, deferred payment, or case-by-case fee negotiations.

What If the Fee Changes Between Now and When I File?

Fee changes take effect on a specific date published in the Federal Register. Applications filed before that date pay the old fee; applications filed on or after the effective date pay the new fee. The postmark or electronic submission timestamp determines which fee applies—not the date you started filling out the form or the date you printed it.

If you're planning to file soon and a fee rule is pending, check the Federal Register for the final rule's effective date. USCIS typically gives 60–90 days' notice between publication and implementation, which is enough time to file under the current fee if you're ready. Rushing an incomplete application to avoid a fee increase, however, increases the risk of rejection or RFE—a false economy that costs more in delays than it saves in fees.

What If I'm Filing as a Military Service Member or Spouse?

Certain military service members and their spouses may qualify for fee exemptions under INA Section 328 or 329. Active-duty service members applying based on qualifying military service during peacetime or periods of hostility file Form N-400 with no fee. Spouses of U.S. citizen service members may also qualify for fee exemptions depending on the service member's deployment status and the applicant's immigration category.

Military fee exemptions are not automatic. You must submit evidence of military service (DD Form 214, service verification letter, or other official documentation) with the N-400. If the documentation is missing or insufficient, USCIS will request the fee—so verify eligibility and gather the evidence before filing. Fee exemptions for military applicants do not cover the cost of document translations, photographs, or legal representation; they eliminate only the $725 USCIS charge.

Payment Methods and What Happens If Payment Fails

USCIS accepts payment by:

• Credit card (Visa, MasterCard, American Express, Discover)
• Debit card with a credit card logo
• Check or money order payable to "U.S. Department of Homeland Security" (no cash)

Online filers pay by card at the time of submission. Paper filers include a check or money order with the mailed application. If a check bounces or a card transaction is declined, USCIS rejects the application and returns the entire package unprocessed. You must refile from the beginning with valid payment—there is no cure period for a failed payment.

Do not send cash. USCIS does not accept it, and mailed cash is not insured or traceable. If you're paying by check, verify that your account has sufficient funds and that the check is made out to the correct payee. A misspelled payee name or an incorrect amount triggers rejection just as surely as a bounced check does.

Additional Costs You May Encounter

Beyond the filing fee and ancillary document expenses, some applicants face costs tied to the substance of their case:

Name change: If you're requesting a legal name change as part of naturalization (permitted under the N-400 process), the court decree is issued at the oath ceremony at no additional government cost. However, updating your name on Social Security records, state-issued IDs, bank accounts, and other legal documents after naturalization can involve fees—some states charge $20–$50 for an updated driver's license, and certified copies of the naturalization certificate itself cost $555 per copy from USCIS if you need extras.

Rehabilitation or waiver for criminal history: If your application requires a waiver of inadmissibility or documentation of criminal rehabilitation, those processes carry separate costs—court fees for obtaining dispositions, fees for expungement petitions, and potentially attorney fees for navigating the waiver process. These are case-specific and not covered by the N-400 filing fee.

Medical or psychiatric evaluations: Applicants with certain immigration or criminal histories may be asked to provide medical or psychiatric evaluations as part of establishing good moral character. USCIS does not reimburse the cost of those evaluations, which can range from $300 to over $1,000 depending on the provider and the scope of the assessment required.

Filing Fee vs. Total Cost: What to Actually Budget

The $725 USCIS filing fee is the fixed cost. The total cost varies based on your case complexity, location, and whether you retain legal counsel. A realistic budget for a straightforward N-400 includes:

• Filing and biometrics fees: $725 (or $0 if waived, $380 if reduced)
• Document preparation (translations, photos, certified copies): $100–$400
• Travel to appointments: $50–$200 (more if you live far from the field office)
• Legal consultation or representation: $250–$3,000+ (optional but common)

Estimated total for a simple case: $900–$1,500. Estimated total for a complex case with legal representation: $2,500–$5,000+. Plan for the higher end if your immigration history includes gaps in U.S. residence, prior arrests, extended foreign travel, or prior visa denials—those cases almost always require legal review to avoid a denial that forces you to start over.

When the Cost Becomes a Barrier to Filing

If the N-400 cost is genuinely unaffordable even with a fee waiver or reduction, consider these strategies:

1. Delay filing until your financial situation improves. Permanent residents are not required to naturalize on any timeline—you can remain a green card holder indefinitely as long as you maintain residence and renew your green card every ten years. Filing when you're financially prepared reduces the risk of abandoning a partially completed application because you can't afford the next step.

2. File the fee waiver even if you're unsure you qualify. USCIS evaluates I-912 requests based on documented income, not subjective financial hardship. If your household income is borderline, file the waiver with full documentation and let USCIS make the call. A denied waiver still gives you the option to pay the fee and proceed; not filing the waiver at all means paying the full amount from the start.

3. Seek assistance from accredited nonprofit organizations. Some community organizations and legal aid societies offer free or low-cost naturalization assistance, including help with fee waiver applications and document preparation. These services don't reduce the government fee, but they reduce or eliminate the cost of legal help. A list of accredited representatives is available on the USCIS website and through local bar associations.

4. Consider the long-term value. Naturalization unlocks federal employment eligibility, removes the risk of deportation, allows unrestricted travel, and grants the right to vote and petition for family members under faster categories. For many applicants, the $725–$1,500 cost pays for itself within months through access to jobs and benefits unavailable to permanent residents.

Why Some Applicants Pay More Than They Should

The most common unnecessary expense in the N-400 process is paying for a second application after the first one is denied or abandoned. Denials happen for preventable reasons: missing evidence, unexplained gaps in the residence timeline, failure to disclose arrests, or skipping the interview without requesting a reschedule. Each of those errors is fixable before filing—but fixing them after USCIS points them out means paying the filing fee again.

An initial consultation with an immigration attorney costs far less than refiling. The Law Offices of Peter D. Chu charges $250 for a naturalization consultation that reviews your eligibility, identifies potential issues, and maps out the evidence you'll need to file a complete application the first time. That $250 is the cost of avoiding a $725 do-over.
