N-600 documents citizenship the applicant already holds. It is filed on its own and is not part of any 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-600 against the rejection reasons USCIS actually applies, before you mail it — $39 against the $1,385 you are about to spend.

How much is the N-600 filing fee in 2026?
The USCIS filing fee for Form N-600 is $1,335 filed online and $1,385 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-600 online?
Yes. Filing Form N-600 online costs $1,335 against $1,385 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 Online filing also gives you an immediate receipt and removes the risk of mailing to a superseded USCIS address.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-600 first.
Does the N-600 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-600 — 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.)
Is the N-600 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.
