The N-400 filing fee is $760—a meaningful cost for many households. USCIS knows this, and that's why the fee waiver program exists. If your income falls at or below 150% of the federal poverty guidelines, you may be able to file your N-400 application for naturalization for free.
This guide explains exactly how the N-400 poverty guidelines work, which income thresholds qualify, how to apply for a fee waiver, and what happens if your waiver request is denied.
The federal poverty guidelines (FPG) are income thresholds published annually by the U.S. Department of Health and Human Services. They're used across dozens of government programs to determine eligibility for assistance. USCIS uses these guidelines as the benchmark for N-400 fee waiver eligibility.
The specific threshold for the N-400 fee waiver is 150% of the federal poverty level. That means if your household income is at or below 1.5 times the poverty guideline for your household size, you can potentially get the $760 filing fee waived entirely.
The federal poverty guidelines change each year, typically in January or February. Always use the most current guidelines when preparing your I-912 fee waiver request. Using outdated figures could make you appear ineligible when you actually qualify—or vice versa.
The 2026 poverty guidelines establish these income thresholds at 150% of the federal poverty level for the contiguous 48 states and D.C.:
For households larger than 8, add approximately $8,070 per additional person to calculate the base poverty guideline, then multiply by 1.5 for the 150% threshold.
Alaska and Hawaii have separate, higher poverty guidelines. If you live in either state, look up the Alaska/Hawaii-specific figures when you apply.
Two routes to eligibility exist under the fee waiver program:
Route 1 — Income below 150% FPG: If your household income falls at or below the 150% threshold for your household size, you can apply for a fee waiver. You'll need documentation of your income—tax returns, W-2 forms, recent pay stubs, or a letter from an employer.
Route 2 — Receipt of qualifying public benefits: If you're currently receiving means-tested public benefits, you automatically qualify for a fee waiver without needing to document your income separately. The qualifying benefits include:
The key word is "currently receiving." You must be actively enrolled in the benefit at the time you submit your fee waiver request, not just a past recipient.
The fee waiver application is Form I-912 (Request for Fee Waiver). This form is filed together with your N-400—not separately. Here's the process:
Step 1: Download the current version of Form I-912 from USCIS.gov. USCIS updates forms periodically, and submitting an outdated version results in rejection.
Step 2: Complete I-912 fully. The form asks for your household size, household income, and the basis for your fee waiver claim (income below 150% FPG, public benefit receipt, or financial hardship).
Step 3: Gather supporting documentation. This varies by basis:
Step 4: Submit I-912 and your documentation along with your completed N-400. Do not send the $760 filing fee—if you submit the fee with a waiver request, USCIS may not process the waiver correctly.
Step 5: Wait for USCIS's determination. USCIS evaluates fee waiver requests as part of intake. If approved, your case moves forward at no cost. If denied, USCIS will notify you and give you an opportunity to pay the fee and continue your application.
A third basis for fee waiver eligibility exists: financial hardship. This is more subjective than the income or benefits routes, and USCIS evaluates it case by case. You'd use this option if your income is slightly above 150% FPG but you have significant circumstances—substantial medical debts, recent unemployment, large family expenses—that make the filing fee genuinely burdensome.
Financial hardship claims require a detailed written explanation and supporting documentation. They're reviewed less favorably than income-based or benefits-based claims, and approval is less predictable. If your income is close to the 150% threshold, it may be worth consulting an immigration legal aid organization to evaluate your specific situation before filing a hardship claim.
USCIS defines household income broadly for the I-912. It includes income from all members of your household—not just the primary applicant. This means if you live with a spouse, a parent, adult children, or other family members, their income counts too.
Income types that generally count:
What generally doesn't count:
If you're uncertain about how to categorize specific income sources, use the instructions document accompanying Form I-912—USCIS provides specific guidance on what to include.
Fee waiver denials happen. When they do, USCIS sends you a notice that your waiver was not approved, along with the reason. You then have an opportunity to submit the $760 filing fee and continue your N-400 application.
Importantly, a fee waiver denial doesn't mean your N-400 is rejected or that you lose your place in the queue in any meaningful way. USCIS holds your application in a pending status while they wait for the fee.
If you believe the denial was in error—say, if USCIS miscalculated your household size or failed to account for a public benefit you're receiving—you can submit a corrected I-912 with clarifying documentation. This adds time to your process but is the right approach if there's a genuine error in the determination.
USCIS's online N-400 filing system accommodates fee waiver requests. If you file online through your USCIS account, the system will prompt you to upload your I-912 and supporting documentation as part of the application process. The process is similar to paper filing but faster and allows you to check your case status more easily.
Not all applicants can file online—certain categories of N-400 filers are only accepted on paper. Check the current USCIS filing instructions to confirm whether your specific situation allows online filing.
Fee waiver processing doesn't significantly delay N-400 cases. USCIS adjudicates fee waiver requests during intake, typically within a few weeks of receiving your application. Your biometrics and interview scheduling proceed based on when your application is accepted, not based on fee payment method.
The one potential timing issue: if your fee waiver is denied and you take several weeks to submit the filing fee, that gap adds to your total processing time. To minimize this, be prepared to pay the fee if needed—keep the $760 available in case the waiver doesn't come through.
Two groups are exempt from the N-400 filing fee entirely, regardless of income:
Military service members and veterans: If you're filing under INA Section 328 or 329 (military naturalization), USCIS waives the filing fee. You must indicate your military status on the N-400 and provide supporting documentation.
Children adopted by U.S. citizens: Certain adoptees filing under the Child Citizenship Act have fee exemptions that vary by circumstance. If you're filing on behalf of an adopted child, review the specific fee instructions in the N-400 filing guide.
These exemptions are separate from the income-based fee waiver program—they apply regardless of household income, and you don't need to file an I-912.
Several mistakes consistently cause fee waiver denials or delays:
Getting the fee waiver right takes about 30-60 extra minutes of document preparation—it's worth every minute if it saves you $760. And once you've successfully filed, focus your preparation energy on the civics test and English portion of the naturalization interview. Those are the components where preparation makes the most difference in your outcome.
Once you've successfully filed your N-400—with or without a fee waiver—the preparation focus shifts to the naturalization interview itself. The civics test and English proficiency components are where most applicants' anxiety lives, and both are genuinely within your control.
The civics test draws from a pool of 100 questions about U.S. history and government. At your interview, the officer will ask 10 of those questions, and you need to answer 6 correctly. The questions are publicly available on USCIS's website—there are no surprises. What trips people up isn't the content difficulty; it's nerves and unfamiliarity with the verbal response format.
Practicing out loud is more valuable than reading the questions silently. Have someone ask you the questions randomly—without you knowing which one is next—and answer verbally. That simulation of the real interview environment is what builds confidence under mild pressure.
Our N-400 application for naturalization practice tests are structured around the USCIS civics question pool and give you timed, randomized practice in the format that matches the real interview. Use them regularly in the weeks before your appointment, and you'll walk into that interview prepared.
The fee waiver gives lower-income applicants genuine access to citizenship—the same rights, the same process, no shortcuts or limitations. If you qualify, use it. The paperwork is straightforward, and the $760 savings is real money that's better spent elsewhere as you build your life as a U.S. citizen.
