What the N-400 Costs and How to Lower It
Roberto Reyes filed his citizenship application in the mid-1990s, and the fee back then was a fraction of what it is today. The cost of naturalizing has climbed steadily, and for many families in California, the filing fee is one of the biggest practical barriers between permanent residence and citizenship. The good news is that USCIS offers both fee waivers and reduced fees, and a significant number of applicants in California are likely to qualify for one or the other.
The N-400 filing fee is what you pay USCIS to process your application, and it generally covers the biometrics step (the fingerprinting and photo appointment that USCIS uses for background checks) rather than billing it as a separate charge. Because this amount can change, check the USCIS N-400 page directly for the current number before you file. If you’re filing by mail, USCIS accepts payment by credit, debit, or prepaid card using Form G-1450, or directly from a U.S. bank account using Form G-1650. For paper filings, USCIS generally no longer accepts personal or business checks, money orders, or cashier’s checks unless you qualify for an exemption (see USCIS filing fees, as of June 2026). If you don’t have access to a bank account or card, you can ask USCIS about requesting an exemption that allows another payment method. If you’re filing online through your USCIS account, you can pay electronically. Payment forms and accepted methods can change, so confirm the current options on the USCIS N-400 page before you file.
For a lot of people, that fee is manageable. For others, especially those on fixed incomes or working in lower-wage jobs, it’s a real obstacle. That’s what the fee waiver and reduced fee options are designed to address.
Fee Waivers Through Form I-912
If you can’t afford the filing fee, you can request a full fee waiver by submitting Form I-912 (or a written fee waiver request with supporting evidence) along with your N-400 application. One important detail: if you’re requesting a fee waiver, you can’t file your N-400 online. You’ll need to file a paper application. USCIS lists three grounds for granting a waiver, and you only need to meet one of them (see USCIS fee waiver guidance, as of June 2026).
The first is receiving a means-tested government benefit. If you’re currently getting Medicaid (Medi-Cal in California), SNAP (CalFresh), SSI, or TANF (CalWORKs), that alone can establish your eligibility for a waiver. You’ll need to include proof, such as a benefit letter or award notice. If you’re receiving any of these benefits, you may also want to visit our page on public assistance programs, which covers how benefits interact with immigration applications more broadly.
The second ground is household income at or below 150% of the Federal Poverty Guidelines. You’ll document this with tax returns, pay stubs, or a letter from your employer. USCIS looks at total household income and household size, but household membership follows specific rules, so not everyone living under the same roof automatically counts. The I-912 instructions spell out who qualifies as a household member. The poverty guidelines update annually, so check the I-912 instructions on the USCIS website for the current thresholds rather than relying on last year’s numbers.
The third ground is extreme financial hardship, documented in writing. This is broader and more subjective. It covers situations where your income might technically be above the threshold, but unexpected expenses, medical bills, a job loss, or other circumstances make paying the fee a genuine hardship. You’ll need to explain the situation in writing and provide supporting documents. USCIS doesn’t publish a precise formula for this category, which means approval is less predictable than the first two grounds, but it exists for exactly the situations where the numbers don’t tell the whole story.
What the Fee Waiver Covers and What It Doesn’t
An approved I-912 waiver covers the N-400 filing fee, which generally means you pay nothing to USCIS to file. Because the fee schedule folds in the biometrics step, an approved waiver usually takes care of that part too, but confirm the current details with USCIS before you rely on it. That’s significant, but it’s worth understanding what a waiver doesn’t cover. If you work with an immigration attorney or accredited representative to help prepare your application, their fees are separate. The waiver is between you and USCIS, not between you and anyone helping you file.
That said, many organizations in California offer free or low-cost help with citizenship applications specifically because the community they serve qualifies for fee waivers. If cost is a concern on both fronts, pairing an approved fee waiver with a free legal clinic can bring your out-of-pocket cost for the USCIS fee and legal help close to zero, depending on whether your waiver is approved and what the clinic offers. Our free and low-cost legal help page can point you toward organizations that do this work.
The Reduced Fee Option
There’s a middle category that often gets overlooked. If your household income is above 150% but less than 400% of the Federal Poverty Guidelines, you may not qualify for a full fee waiver, but you can request a reduced filing fee. You make this request directly on Part 10 of the N-400 application itself, so there’s no separate form to fill out. Like fee waiver requests, reduced fee requests require a paper filing, so you can’t file your N-400 online if you’re requesting the reduced fee (see USCIS reduced fee guidance, as of June 2026).
The reduced fee is lower than the standard amount, though the exact number changes, so verify it on the USCIS filing fees page (as of June 2026) before you file. You’ll need to document your income, with tax returns or pay stubs showing where your household falls relative to the poverty guidelines. Form layouts and thresholds are tied to the current N-400, so confirm the Part 10 line reference and the income ceiling on the USCIS N-400 page when you file.
This option matters because a lot of working families in California fall into precisely this range, earning too much for a full waiver but not enough that the standard fee feels comfortable. It’s one of those details that admissions offices and community organizations don’t always volunteer, so it’s worth asking about directly if your income is in that zone.
California Context
California has a higher concentration of citizenship-eligible permanent residents than any other state, and a correspondingly large network of nonprofit organizations that help with naturalization. Many counties run periodic citizenship workshops, sometimes called “citizenship days” or “naturalization clinics,” where you can get help with your application and your fee waiver request at the same time. These events are often free and staffed by attorneys or DOJ-accredited representatives.
Because California’s cost of living is high relative to the Federal Poverty Guidelines, which are set nationally, a larger share of applicants here may fall into the fee waiver or reduced fee range than the raw income numbers might suggest. The hardship ground on the I-912, in particular, can account for California-specific expenses like housing costs that would be unremarkable in other states.
Next Steps
Start by checking where your household income falls relative to the current Federal Poverty Guidelines on the USCIS I-912 page. If you’re receiving Medi-Cal, CalFresh, SSI, or CalWORKs, gather a recent benefit verification letter, because that’s typically the fastest path to an approved waiver. If your income is above 150% but less than 400% of the guidelines, you can request the reduced fee directly on Part 10 of the N-400 when you file. For help preparing your application or fee waiver request, check our directory of free and low-cost legal services in California, where many organizations assist with citizenship filings at no charge. And if your situation involves any complication beyond a straightforward filing, talking to a qualified immigration attorney or accredited representative before submitting is time well spent.
