Is H1 & H4 approval mandatory before I765 Approval

Hi Anil & Experts
I read/heard somewhere that if both H1 & H4 are not approved USCIS is not approving I765. Is that correct?
Please confirm. My H1 is approved but my wife’s H4 is still pending (OBVIOUSELY). My I765 (C -9 category) based on pending I485 Filed Date is 10/13/2020 and I haven’t heard anything about my case yet. No biometrics, or EAD. Raised Service Request but got the standard response. Then Raised the Expediate Request which was obviously denied.

Anybody on the same boat??

I485 EAD approval is not dependent on H4 approval. It can be approved without H4 also.
