USCIS scheduled an appointment to take your fingerprints and photo. The notice gives the date, time and location -- attendance is required, and the appointment is assigned, not chosen.
What happens next
Attend with the notice and photo ID. If the date does not work, request a reschedule before the appointment rather than skipping it.
Official USCIS wording
On September 9, 2022, we scheduled you for a biometrics appointment and sent you an appointment notice for Receipt Number XXXXXXXXXXXXX. Please follow the instructions in the notice. If you do not receive your appointment notice by October 9, 2022, please go to www.uscis.gov/e-request to request a copy of the notice. If you move, go to www.uscis.gov/addresschange to give us your new mailing address.
