The USCIS announced its fee schedule final rule. That rule will go into effect after the initial registration period for the FY 2025 H-1B cap. Therefore, the registration fee during the registration period starting in March 2024, will remain $10. , USCIS recently announced a final rule that will increase the filing fee for Form I-907, to adjust for inflation, effective Feb. 26, 2024. If USCIS receives a Form I-907 postmarked on or after Feb. 26, 2024, with the incorrect filing fee, we will reject the Form I-907 and return the filing fee. For filings sent by commercial courier (such as UPS, FedEx, and DHL), the postmark date is the date reflected on the courier receipt.  The rule is effective February 26, 2024. 

Compliance date: Requests for premium processing postmarked on or after February 26, 2024 must include the new fee.

The increases for the premium processing fees is to reflect the amount of inflation from June 2021 through June 2023 according to the Consumer Price Index for All Urban Consumers.

Note the genealogy forms G-1041, G-1041A and G-1566 do not appear to be affected by the proposed increase in fees.
