I think you are in the same situation. There are only 2 scenarios
1. Does H4 need to be processed (i.e. new, renewal or extension, or change from another status to H4) along with EAD?
2. Or only EAD needs to be processed i.e. H4 is already approved. This scenario is getting processed faster.
We did biometrics on June 13th and you guys did a day later. Maybe that's the difference or maybe the adjudicator working on your case is a little slower. Either way, I think you will get approval this week.
Best of luck!
