Current status when H4 approved after H1B approval, H4 withdrawal request pending

@anil_am22 we are in the same boat where my wife’s h1 got approved in September 2020 and we sent in the withdrawal for H4 and H4-EAD months ago in September 2020 and again this year. But uscis didn’t process the withdrawal at all and now H4 is all of a sudden approved and she is in H4 status and working with H4 EAD.

Her company is going to file a new H4 to H1 COS ASAP in premium but I had the following questions

  • what happens if USCIS withdraws the H4 application now before the H1 COS is approved or filed?

  • will she be out of status? Will she be able to get back to H1B at all?

  • we also have our EAD from I485 application. When should we use that and if we do then can she get back to H1B status?

@anil_am22 would really appreciate your input here. Thanks a lot.
