I am curious if anyone has found themselves in this situation Application recieved 01/25/2021 and ext letter 1/28/2021 not a single notice since, no notice we are using your prior Biometrics, no appointment, Nothing, Status is Case being processed. I am confused about not getting some sort of notice RE: Biometric's , every other timeline I see there was either a notice of using prior or an appointment within 3 months... we have nothing at all, Anyone else have this happen?
