USCIS announced that filing fees are going to be raised on November 23, 2010. There will be an average 10% increase on fees, except the current naturalization application fee will remain unchanged. The USCIS is introducing three new fees (see below).
Copied from USCIS:
SUMMARY: The Department of Homeland Security (DHS) is adjusting the fee schedule for U.S. Citizenship and Immigration Services (USCIS). USCIS conducted a comprehensive fee study, refined its cost accounting process, and determined that current fees do not recover the full costs of services provided. DHS has found that adjustment to the fee schedule is necessary to fully recover costs and maintain adequate service. In response to comments, several adjustments were made to the proposed rule published on June 11, 2010.
In this final rule, DHS: increases the fees by a weighted average of 10 percent; establishes three new fees covering USCIS costs related to processing the Regional Center Designation under the Immigrant Investor Pilot Program, Civil Surgeon Designation, and DHS Processing of Immigrant Visa requests; and adjusts the premium processing service fee by the percentage increase in inflation according to the Consumer Price Index–Urban Consumers (CPI-U) published as of July 2010. This rule also finalizes the interim rule that established the premium processing service and fees.
DATES: This rule is effective November 23, 2010. Applications or petitions mailed, postmarked, or otherwise filed on or after November 23, 2010 must include the new fee.
