N-400 fees and fee waivers, explained
Applying for citizenship comes with a government filing fee, and for a lot of people that cost is the scariest part of the whole process. The good news is there are real ways to lower it or skip it entirely if money is tight. Here is how the fee works, how you pay it, and what to do if you genuinely cannot afford it.
The filing fee, and why online is usually cheaper
When you file Form N-400, USCIS charges a filing fee to process your application. The exact amount changes from time to time, so the only number you should trust is the one published on uscis.gov — look at the N-400 fee page or the USCIS fee schedule before you do anything else. Do not rely on what a friend paid last year or what an old article says, because those figures go stale fast.
One thing that stays fairly consistent is that filing online through a USCIS account is generally a little cheaper than mailing in a paper application. It is a small discount, but it is free money in your pocket, and the online system also catches some mistakes before you submit. If you are comfortable on a computer or have someone who can help you, the online route is usually the better deal.
How you actually pay
If you file online, you pay the fee right there in your USCIS account at the end, using a debit card, credit card, or a bank withdrawal. The system walks you through it step by step, and once the payment goes through you will get an electronic confirmation. Save that confirmation — a screenshot or a printout is fine — because it is your proof that you paid.
If you file on paper, you send your payment in with the application. You can pay by check or money order made out to U.S. Department of Homeland Security, or include a completed Form G-1450 to charge a credit card. Whichever way you go, double-check the amount against the current fee on uscis.gov, since a wrong amount can get your whole package rejected and sent back to you.
Fee waivers: when you genuinely cannot afford it
If paying the fee would be a real hardship, you can ask USCIS to waive it completely by filing Form I-912 along with your N-400. A waiver means you pay nothing at all for the application. There are three ways to qualify, and you only need to meet one of them.
The first is receiving a means-tested public benefit — programs like Medicaid, SNAP (food stamps), or TANF that are given based on low income. The second is having a household income at or below a set percentage of the Federal Poverty Guidelines; the exact threshold depends on your household size and changes over time, so check the current figures on uscis.gov rather than guessing. The third is financial hardship, such as large medical bills, recent job loss, or other costs that make it impossible to pay even if your income looks okay on paper.
How to request a waiver, and that it will not hurt you
To request a waiver, you fill out Form I-912 and file it together with your N-400 — not after, but in the same package or online submission. Then you back up your claim with documents: a benefit approval letter if you receive a means-tested benefit, tax returns or pay records if you are using the income test, and bills or statements if you are claiming hardship. The clearer your paperwork, the smoother the review tends to go.
Here is the part people worry about most, so let it sink in: asking for a fee waiver does not count against you. It has no effect on whether your application is approved, and it does not hurt your good moral character finding. USCIS created the waiver on purpose so that cost would not lock people out of citizenship, and using it is completely legitimate.
Reduced fees and a few practical tips
Separate from a full waiver, some applicants who earn a bit too much to qualify for a waiver may still be eligible for a reduced fee based on income. Whether this option exists, who qualifies, and how much it costs are all things that change, so confirm the current rules and amounts on uscis.gov before counting on it. If a full waiver feels out of reach, it is worth checking whether a reduced fee applies to you.
A few habits that make life easier: file online when you can to get the lower fee and built-in error checks, and always keep your payment receipt or fee-waiver confirmation in a safe place. Most of all, do not let the cost alone stop you from applying — between waivers and reduced fees, there is almost always a path forward if you are otherwise eligible. Start by reading the current N-400 fee page so you know exactly what you are dealing with.
This is general information, not legal or financial advice — fees, income thresholds, and eligibility rules change, so confirm the current fees and rules at uscis.gov before you file.
