How much does it really cost to become a U.S. citizen? If you have started filling out the N-400, Application for Naturalization, you have probably noticed that the fee gets almost as much attention as the civics test. And for good reason. The N-400 naturalization fee is one of the largest single payments many applicants ever make to the immigration system, and getting it wrong can delay a case by weeks or sink it entirely.
This guide breaks down what the fee is, who pays what, how to pay it safely, and where applicants most often stumble. It also flags the one thing every reader should do before mailing a check: confirm the current amount on the official fee schedule, because fee rules change and have been challenged in court before.
What the N-400 Fee Covers
The N-400 is the form a lawful permanent resident files to request U.S. citizenship. The fee attached to it is not a processing surcharge on top of something else. It funds the entire adjudication: receipt and data entry, FBI fingerprint and background checks, the interview with a USCIS officer, the English and civics tests, and the final decision.
Under the fee rule that took effect on April 1, 2024, the structure changed in two important ways. First, the separate $85 biometrics fee was eliminated for most applicants, so fingerprints are now covered inside the main fee. Second, USCIS introduced a lower price for people who file online rather than on paper.
That means the same application can cost two different amounts depending on how it reaches the agency. The table below summarizes the structure that has applied since the 2024 rule.
| Filing situation | Fee amount | Notes |
|---|---|---|
| Online filing (Form N-400) | $760 | Standard rate for most applicants |
| Paper filing (mailed N-400) | $710 | Lower than online under the 2024 rule |
| Reduced fee (household income at or below 400% of the Federal Poverty Guidelines) | $380 | Requires the reduced-fee request with supporting evidence |
| Full fee waiver (Form I-912) | $0 | For means-tested benefit recipients, income at or below 150% of the guidelines, or financial hardship |
One detail trips people up constantly: the online option is the more expensive one. Most government services discount electronic filing, so applicants assume USCIS does too. It does not, at least not under the current schedule. If cost is the deciding factor and you are comfortable with paper, mailing the form can save $50. If speed and receipt tracking matter more, filing online is usually worth the difference.
How the Fee Has Changed Over Time
Naturalization fees have climbed steadily for nearly two decades. The N-400 cost $595 in 2007, rose to $640 in 2016, and was restructured in 2020 in a rule that was later partly blocked in litigation. The 2024 rule then set the current $710 and $760 figures and folded biometrics into the base price.
That history matters for two reasons. First, it explains why older guides, forum posts, and YouTube videos quote numbers that no longer apply. Second, it shows that the fee is set by regulation, not by a fixed statute, which means it can move again. Anyone who bookmarked a fee page two years ago should treat that number as unreliable.
A practical habit: check the fee on the day you write the check or enter card details, not the day you started preparing the packet. Preparation can take months, especially if you are gathering tax transcripts and travel records.
Who Qualifies for the Reduced Fee or a Waiver
Not everyone pays the full amount. The 2024 rule created a reduced fee tier and kept the long-standing fee waiver, and both are underused because applicants assume they will not qualify.
The reduced fee
If your household income is at or below 400% of the Federal Poverty Guidelines, you may request the reduced fee of $380. The request goes in with your N-400, supported by documentation such as tax returns or evidence of income. This tier is broader than many people expect. A family of four with a moderate income can fall inside it, so it is worth checking the current poverty guidelines against your household size before assuming you pay full price.
The full fee waiver
A complete waiver through Form I-912 remains available in three situations:
- You receive a means-tested benefit, such as certain Medicaid coverage, SNAP, or Supplemental Security Income.
- Your household income is at or below 150% of the Federal Poverty Guidelines.
- You face financial hardship, such as unexpected medical bills or unemployment, that prevents payment.
The waiver is not automatic. USCIS reviews the evidence, and a denied waiver without a corrected filing can lead to a rejected application.
What is not covered
The N-400 fee does not include legal representation, document translation, passport photos, or test preparation classes. Applicants who hire an attorney should budget separately, and those costs vary widely. The filing fee also does not cover the cost of replacing a lost green card or filing other forms that may come up along the way.
How to Pay Without Causing a Rejection
Payment errors are among the most avoidable reasons an N-400 gets rejected at the lockbox. The application is returned, the clock resets, and in some cases the fee itself is lost to a bad instrument.
USCIS accepts credit and debit cards, personal checks, and money orders. Online filings require electronic payment. A few rules of thumb that hold up in practice:
- Write the exact amount. A check for the wrong figure, even by a few dollars, can trigger rejection. Confirm the amount the same day.
- Make the check payable correctly. Use the full official payee name listed in the form instructions, not an abbreviation.
- Sign and date the check. Unsigned checks are returned.
- Do not staple or tape the payment to the form. Use a paper clip or place it loose in the packet as instructed.
- Keep a copy. Photograph both sides of the check or money order before mailing. If the payment is lost, that image is your proof.
- Do not combine fees for multiple forms on one check unless the instructions explicitly allow it.
If a payment fails, USCIS will generally attempt to resubmit once. A second failure usually means the application is rejected and returned. For applicants juggling tight budgets, that is a strong argument for a money order or a card with a confirmed balance rather than a check that might bounce.
Common Mistakes That Cost Applicants Money
Beyond payment mechanics, several recurring errors show up again and again.
Paying the old amount. The most common mistake is using a fee figure from a pre-2024 guide. The $640 and $725 numbers are obsolete under the current schedule.
Missing the reduced-fee request. Applicants who qualify for the $380 tier but file without the request pay the full amount and cannot get the difference back afterward. The request must accompany the original filing.
Assuming a waiver covers everything. A fee waiver removes the filing fee, but it does not exempt an applicant from the English or civics requirements, or from providing biometrics if requested.
Filing on paper to save $50 without checking processing times. The savings are real, but paper filings generally take longer to receipt, and the difference can matter for applicants with travel planned or deadlines tied to a green card anniversary.
Ignoring the broader cost picture. The filing fee is one line item in a process that may also involve attorney fees, translation, travel to a field office, and time off work. Applicants who budget only for the N-400 itself are often surprised.
Where the Fee Fits in Immigration Policy
Naturalization is not the only immigration payment applicants face, and comparing them helps put the N-400 in context. A green card renewal, a work permit, and a change of status each carry their own fees, and several of them rose in the same 2024 rule. Applicants who are also tracking other costs, such as the ongoing debate over Apple’s 27 percent App Store fee in 2026, will recognize the pattern: platform and regulatory fees tend to rise quietly and compound over time.
For anyone preparing for the English and civics portions of the interview, free study tools are widely available, and some applicants use AI voice tools to practice speaking aloud.

Practical Tips That Actually Help
Applicants who get through the fee stage smoothly tend to share a few habits.
They build a small buffer. Adding $20 to $50 to the budget covers a money order fee, passport photos, or a last-minute document request without scrambling.
They file the reduced-fee or waiver request even when they are unsure. A denied request usually means USCIS issues a request for evidence or accepts the full fee, not that the case is thrown out. Filing without the request when you qualify is the worse outcome.
They keep a complete copy of the packet. If USCIS says the fee was missing, a copy of the check and the mailing receipt resolves the dispute far faster than starting over.
They check the fee on the official schedule the week they file, not the week they started. Fee rules have been litigated before, and a regulation can change between preparation and submission.
Finally, they read the form instructions rather than relying on forums. The instructions specify the current amount, the payee, and the acceptable payment methods, and they are updated when the rules change. For a payment this large, the primary source is always the safer bet.
Conclusion
The N-400 naturalization fee is a real financial hurdle, but it is also one of the most predictable parts of the citizenship process. Under the current schedule, most applicants pay $760 online or $710 on paper, with a reduced fee of $380 available to households at or below 400% of the Federal Poverty Guidelines and a full waiver through Form I-912 for those who qualify.
The applicants who struggle are rarely the ones who could not afford it. They are the ones who used an outdated figure, skipped a reduced-fee request they were entitled to, or mailed a check that failed. Confirm the amount the day you file, document your payment, and treat the official instructions as the final word. Do that, and the fee becomes a line item rather than an obstacle.
Frequently Asked Questions
How much is the N-400 fee in 2026?
Under the fee rule that took effect on April 1, 2024, the standard N-400 fee is $760 for online filing and $710 for paper filing. A reduced fee of $380 is available to applicants with household income at or below 400% of the Federal Poverty Guidelines. Because fee rules can change by regulation, applicants should confirm the current amount on the official USCIS fee schedule before paying.
Why is online filing more expensive than paper filing?
The 2024 fee rule set a higher price for online N-400 filings and a lower one for paper. This is the reverse of what most people expect, since many government agencies discount electronic filing. Applicants who want to save $50 can file on paper, though paper filings generally take longer to receipt.
Can I get the N-400 fee waived completely?
Yes, in some cases. A full fee waiver through Form I-912 is available to applicants who receive a means-tested benefit, whose household income is at or below 150% of the Federal Poverty Guidelines, or who face financial hardship such as unexpected medical bills or unemployment. The waiver requires supporting evidence and is reviewed by USCIS; it is not granted automatically.
What happens if I pay the wrong amount?
If the fee is incorrect, USCIS will typically reject the application and return it, which resets the process and can cost weeks. A check that bounces or fails a second time usually results in rejection as well. To avoid this, confirm the exact amount on the day you file and keep a copy of your payment instrument.
Does the N-400 fee include biometrics and the interview?
Yes. Under the 2024 rule, the separate $85 biometrics fee was eliminated for most applicants, so fingerprinting is covered inside the main N-400 fee. The fee also funds the interview, background checks, and the English and civics tests. It does not cover attorney fees, translation, passport photos, or test preparation.
Can I get a refund if my application is denied?
Generally, no. Filing fees are charged for adjudicating the application, not for approving it, so a denial does not trigger a refund. This is one reason applicants should review eligibility carefully and, where possible, consult a qualified representative before filing rather than after a denial arrives.
