I raised several SR's in the past but recently opened one on Nov 19 and got this below response.
The status of this service request is:
We researched your case and found that your case is currently in line for processing. We process cases in the order in which they are received and will assign your case to an officer for review as soon as possible. We regret that we cannot provide a definitive timeframe on the processing of your application, but assure you that we are committed to the timely processing of applications for employment authorization.
and got the approval on both H4 and H4 ead on dec 3.
and one more suggestion form myside, if you haven't opened online usicis account yet, open one. I know this does not make sense but I opened one 2 weeks back after reading several blogs saying that status updates were showing up on account page instead of regular uscis case status page.
