All receipts for payment of Machine-Readable Visa (MRV) fees issued before October 1, 2022, will expire September 30, 2023.  There will be no extensions of fee validity.  Applicants must schedule an appointment or submit an interview waiver application before September 30, 2023 to avoid paying a new fee.  Please note that the interview itself does not need to take place before September 30, 2023, but an interview appointment needs to be made in the system, even if it is scheduled months into the future.  Furthermore, applicants using MRV fees paid before October 1, 2022 to book an appointment are cautioned not to attempt to change their appointment dates on or after October 1, 2023.  Doing so will result in forfeiture of both the original appointment slot and the MRV fee receipt.  The applicant will be required to pay a new fee and submit a new application package.
