Status not changed after giving the biometrics

My son and myself had given biometrics on November 2020 in Texas Service Center. Though my status changed to Fingerprints updated, my son’s status is showing still “Case Received”. I tried calling couple of times to USCIS but couldn’t talk to any representatives.
What number should I call to inquire about this?

Also does anyone has any clue, how long we need to wait for after biometrics.

Its okay even if your son’s status does not change.

USCIS system does not always update the status for all applicants.

No need to worry if your son also gave the fingerprints. The USCIS system would have recorded them irrespective of the status update.
