N400 Fees
- On June 23, 2026, DHS proposed increasing the Form N-400 paper filing fee from $760 to $1,330 and the online filing fee from $710 to $1,280.
- DHS proposed to eliminate the current $380 reduced fee option for low-income applicants and end fee waiver eligibility for both Form N-400 and Form N-336.
- Increased fees are not yet effective as of end of July, 2026 but may be effective in September, 2026. Please check current fee.
- Online filing of the N-400 is cheaper than paper filing, gives an instant receipt, and the Green Card extension is immediately available. A USCIS account is needed, with your email address and a password. Bank payment for fee is required and is paid online.
