The N-400 Application for Naturalization currently carries a filing fee of $760 (as of the most recent USCIS fee schedule). For many applicants — especially those who've been working lower-wage jobs, raising families, or managing medical expenses — that's a significant barrier. USCIS recognizes this and offers a reduced fee option for eligible applicants.
The N-400 reduced fee is exactly what it sounds like: a lower filing fee for applicants who meet specific income criteria. It's not a full waiver — you still pay something — but the reduced amount is substantially lower. Understanding whether you qualify, what documentation you need, and how to request it properly can save you hundreds of dollars on your naturalization application.
USCIS sets eligibility for the reduced fee based on household income relative to the Federal Poverty Guidelines (FPG). To qualify, your household income must be:
In plain terms: if your income is too high for a fee waiver (below 150% FPG) but not high enough to make the full $760 fee easy to absorb (above 400% FPG), you fall in the middle range that qualifies for the reduced fee.
The Federal Poverty Guidelines are updated annually, so the exact income thresholds change each year. USCIS publishes the current income cutoffs on their website. For a single-person household, the 400% FPG figure is roughly $58,000–$60,000 per year in recent years, though the exact number depends on the current guidelines when you file.
The reduced N-400 fee is currently $460 — a savings of $300 from the standard $760 fee. This reduced rate reflects USCIS's recognition that naturalization is a meaningful civic step, and financial hardship shouldn't be an insurmountable obstacle for people who qualify on the merits.
Note that biometrics are included in the N-400 fee as of the updated fee schedule — you don't pay a separate biometrics fee on top of the filing fee. This applies to both the standard and reduced fee amounts.
You don't file a separate form to request the reduced fee. Instead, you indicate your request directly on the N-400 application. Here's how the process works:
Calculate your total household income for the previous tax year (or the most recent 12 months if filing mid-year). Include all household members' income — not just your own if you have a spouse or dependents living with you. Compare this total to the current Federal Poverty Guidelines for your household size.
USCIS's website includes a chart showing the income brackets for different household sizes. If your income falls between 150% and 400% of the FPG for your household size, you may qualify for the reduced fee.
You'll need to document your income to support the reduced fee request. Acceptable documentation includes:
USCIS doesn't require you to submit all of these — use whatever you have that clearly establishes your household income. A combination of the most recent tax return and recent pay stubs is typically the most straightforward evidence package.
When filling out your N-400, look for the fee selection section. You'll indicate that you're requesting the reduced fee and submit the required income documentation along with your application package.
Pay the reduced fee amount ($460) rather than the standard fee. Sending the wrong payment amount — or sending the standard fee when you meant to request the reduced fee — can delay processing. Be deliberate about this step.
Your application package should include the completed N-400, supporting eligibility documents (permanent resident card, passport photos, supporting documents for your specific situation), the income documentation supporting your reduced fee request, and your fee payment for $460.
If you're filing online through a USCIS account, the system will prompt you through the fee selection process. If filing by mail, follow the N-400 instructions for document assembly.
These are two distinct options — and many applicants confuse them.
A fee waiver (Form I-912, Request for Fee Waiver) eliminates the filing fee entirely. You can request a fee waiver if you receive a means-tested public benefit (like Medicaid, SNAP, or SSI), if your income is at or below 150% of the FPG, or if you can demonstrate financial hardship based on your specific circumstances.
The reduced fee doesn't require a separate waiver form — it's built into the N-400 application itself for the income band between 150% and 400% FPG.
If you think you might qualify for a full fee waiver, it's worth checking before defaulting to the reduced fee. The I-912 has its own documentation requirements, but if your income truly qualifies, paying $0 is better than paying $460.
Applicants who get tripped up on the N-400 reduced fee typically make one of a few errors:
Using outdated FPG tables. The Federal Poverty Guidelines update annually in the spring. If you're using an old chart to check your eligibility, you might have the wrong thresholds. Always use the current-year guidelines from the U.S. Department of Health and Human Services website.
Underestimating household income. USCIS looks at total household income — all adults living with you who contribute financially, not just the applicant's income. If you include only your own earnings and your spouse also works, your calculation will be wrong.
Failing to include income documentation. Requesting the reduced fee without the supporting income evidence will likely result in your application being rejected or returned. The documentation is not optional.
Sending the wrong fee amount. If you want the reduced fee, send $460. If USCIS receives $760 and you intended the reduced fee, there's no mechanism to get the difference back easily. Double-check your payment before sending.
USCIS will review your income documentation along with the rest of your application. If they determine you don't qualify for the reduced fee, they'll likely send you a request for evidence (RFE) or a rejection notice asking you to pay the full fee. This is uncommon if you've documented your income correctly, but it can happen if the documentation is incomplete or ambiguous.
If everything is in order, USCIS will process your application at the reduced fee rate. Your receipt notice, biometrics appointment, and interview scheduling will proceed through the normal process — the reduced fee doesn't change any other aspect of how your application is handled.
Processing times for N-400 applications vary considerably by field office — from a few months to well over a year depending on your location and USCIS workload. Check USCIS's published processing times for your specific office to set realistic expectations.
Filing the N-400 is the start, not the end, of your naturalization journey. After filing, you'll need to prepare for the naturalization interview and civics test. The civics test covers 100 civics questions — at your interview, an officer will ask you up to 10 of them, and you need to answer at least 6 correctly.
You'll also be tested on your ability to speak and understand English (unless you qualify for an exemption based on age and years of residency). The interview covers your N-400 application in detail — be prepared to answer questions about your background, travel history, and moral character questions truthfully and clearly.
Preparation matters. Use practice tests and study materials to build confidence on the civics content and to review what the interview will cover.
If you qualify for the N-400 reduced fee, take advantage of it — that $300 savings is real money. The key is gathering your income documentation before you file so it's ready to include with your application package. A tax return plus a few recent pay stubs is usually all you need.
While you're preparing your application, start working on the civics test too. The naturalization interview comes faster than many applicants expect, and the civics test requires genuine preparation — not just a quick review the night before. Consistent practice with the 100 official civics questions builds the retention you'll need when an officer is asking them face-to-face.
