This tool will ask questions to help determine your fee; however, it does not store answers to the questions or any other personal information.
USCIS developed the Fee Calculator to help reduce the number of rejected applications due to incorrect filing fees. This calculator will always have the most up-to-date fee information and can determine the exact filing fees for any form processed at a USCIS Lockbox Facility.
