$1,330 would become the new paper filing fee for U.S. citizenship under a DHS proposal, up 75% from $760, while the online fee would rise 80% to $1,280.
DHS said current naturalization fees do not cover the full cost of adjudication, screening and vetting, and argued applicants should bear those costs instead of other immigration forms subsidizing them.
The rule would also scrap reduced N-400 fees for households at or below 400% of federal poverty guidelines and end fee waivers, though current and former military applicants would keep exemptions.
The increases are not yet in effect and must clear the federal rulemaking process, including a public comment period, before they can be enacted.
The proposal marks a break from past administrations that kept naturalization fees lower to encourage citizenship, and critics say it could price some green-card holders out of applying.
