Fees shown are taken from USCIS Form G-1055, edition 05/29/26, verified by hand on 2026-07-11. USCIS changes fees without notice — confirm your exact total at the official USCIS fee calculator before you file. Filing fees only: they exclude attorney fees, premium processing, and Department of State fees.

A rejected package costs you this fee and the wait

USCIS returns a rejected filing with the fee — but you lose the months you already waited, and priority dates and status gaps do not pause while you refile. FormGuard checks a completed N-600 against the rejection reasons USCIS actually applies, before you mail it.

Paper or online?

Filing N-600 online costs $1,335 against $1,385 on paper — a $50 difference. Online filing also confirms receipt immediately and removes the risk of mailing to a superseded address. Not every applicant or category is eligible to file online; check the official form page below.
