USCIS posted a notice in the federal register regarding the fee increases which were proposed to take effect in 2020. According to USCIS,
The Department is complying with the terms of these orders and is not enforcing the regulatory changes set out in the Final Rule. USCIS will continue to accept the fees that were in place prior to October 2, 2020, and follow the guidance in place prior to October 2, 2020 to adjudicate fee waiver requests as provided under the Adjudicator’s Field Manual (AFM) Chapters 10.9 and 10.10.https://www.federalregister.gov/documents/2021/01/29/2021-02044/us-citizenship-and-immigration-services-fee-schedule-and-changes-to-certain-other-immigration
The Biden Administration is not expected to push for these fee increases, but may propose different ones in the future as necessary.
