N-400 is normally filed on its own. It is the last step for a green card holder rather than part of a package.
Each form on this list is billed separately — the amounts add up rather than combining into one package price. Confirm your own list against the official form instructions before you file.
A rejected filing comes back with the fee — but you lose the months you already waited, and priority dates, status gaps and work-permit gaps do not pause while you refile. A denial is worse: the case was accepted and adjudicated, so USCIS keeps the fee. Since 10 July 2026 a signature defect on a paper filing can be denied outright, with no chance to correct it. FormGuard checks a completed N-400 against the rejection reasons USCIS actually applies, before you mail it — $39 against the $760 you are about to spend.

How much is the N-400 filing fee in 2026?
The USCIS filing fee for Form N-400 is $710 filed online and $760 filed on paper. That is the figure on the current G-1055 fee schedule, edition 10/07/26. It covers the USCIS filing fee only — not attorney fees, premium processing, or any fees collected by the Department of State.
Is it cheaper to file N-400 online?
Yes. Filing Form N-400 online costs $710 against $760 on paper — a saving of $50. Online filing also gives you an immediate receipt and removes the risk of mailing to a superseded USCIS address. Not every category is eligible to file online, so check the official USCIS page for N-400 first.
Does the N-400 fee include biometrics?
Yes. Since the USCIS fee rule that took effect on April 1, 2024, there is no separate biometric services fee for Form N-400 — biometrics is included in the filing fee shown above. (A separate $30 biometrics fee still applies to a small number of request types, such as Temporary Protected Status filings.)
Who pays a reduced N-400 fee, and who is exempt?
The G-1055 schedule lists these situations for Form N-400: Reduced fee — household income not more than 400% of the Federal Poverty Guidelines (paper only) — $380. A reduced or waived fee applies only if you actually meet the stated condition. Claiming one you do not qualify for is a rejection reason, not a discount.
Is the N-400 filing fee refundable if USCIS rejects or denies my form?
These are two different outcomes. If USCIS rejects your filing, the case was never accepted — USCIS returns the package and the filing fee, but you lose the months you already waited and have to start again. If USCIS denies your case, it was accepted and adjudicated, and the filing fee is not refunded. Filing it correctly the first time is what protects both the fee and the timeline.
