Will H4 EAD be approved if we raise service request with USCIS?

Has anyone called USCIS after the processing date mentioned?

currently says Oct-8 2018

Has anyone tried calling who applied before Oct 8, if yes any update please?

Lot of people call USCIS and raise a service request.

USCIS would send a status update request to the case officer working on this case and the chances are high that your case may get approved a little earlier.

Better to call or raise service request online?

Both are same. Online or call ends up with same service request.
