N-400 fee could rise to $1,330 under a June 2026 DHS proposal

On 23 June 2026 the Department of Homeland Security published a proposed rule in the Federal Register that would almost double the fee for Form N-400, the application for US citizenship. The paper filing fee would go from $760 to $1,330 and the online fee from $710 to $1,280. The proposal would also remove the $380 reduced fee for applicants whose household income is at or below 400 percent of the Federal Poverty Guidelines, and it would end fee waivers for the N-400.

What else is in the proposal

Form N-336, used to ask for a hearing after a naturalisation application is denied, would rise from $830 to $1,475 on paper and from $780 to $1,425 online, and fee waivers for that form would also end. Current and former members of the US armed forces who qualify under the military naturalisation provisions would still pay nothing, because the law requires that exemption. DHS says the aim is to bring these fees closer to what it costs USCIS to process the forms.

Written comments were accepted until 24 August 2026 under docket USCIS-2026-0265. A proposed rule does not change any fee by itself. DHS must publish a final rule, with an effective date, before new fees apply. The USCIS fee schedule (Form G-1055, edition dated 26 October 2026) still lists the N-400 at $760 on paper, $710 online and $380 for the reduced fee.
