USCIS has launched Form I-912, Request for Fee Waiver, to allow applicants and petitioners to request fee waivers for a variety of requests and services. This waiver can be applied to biometric service fees and Form N-400, Application for Naturalization. The waiver is also applicable to Form I-485, Petition for Adjustment of Status, but in limited circumstances. The fee waiver is not applicable for petitions that require you to prove that you are not likely to become a public charge, such as I-485s based on an approved I-130, I-140, or entry as a fiancee.
Requests for fee waiver will be reviewed on a case-by-case basis and will require the requester to provide details and evidence supporting their fee waiver request.
