Biometrics Appointment Was Scheduled
Employment-based green card petition
What this means
USCIS scheduled your biometrics appointment. At the ASC they take fingerprints, a photo, and a signature used for background checks.
What to do next
Attend on the date and time on the notice. Bring the appointment notice and government photo ID. If you cannot go, reschedule through myUSCIS or the instructions on the notice — missing it can delay your case.
