I presently have H1 to F1 COS pending which recently got an RFE which I am addressing. After I filed for this COS I stopped working and eventually my employer revoked my H1. I am presently attending classes and unfortunately have some unexpected change in plans and would like to go back to H1. Since, I have a F1 COS in process can I file for a new H1 with a new employer as well in parellel?
