H1B Transfer filing while another H1B transfer on Regular is pending

[Sak23]

I have a question on H1B transfer filing. Employer A filed a H1B transfer through Regular processing and I have started working with Employer A. Employer B willing to file a H1B transfer in premium processing. I would like to know whether any RFEs will be issued for the H1B petitions filed through Employer A and B. What is the chance of approval for both H1B's.

You will receive RFE's only if your paperwork has not been filed properly with the correct documents.

In such situations an approval may also be possible even without RFEs if the beneficiary's last approved I-797 Approval Notice has not expired.

Thanks for the reply.  My last approved I-797 approval notice is not yet expired and currently working for Employer A through H1B regular filing with receipt notice.
Employer B is planning to file H1B in premium processing. I have a question on the below scenarios.
If the petition filed through Employer B is approved through Premium processing and petition filed through employer A in regular processing is not approved.
The period I worked through Employer A in regular processing is considered to be out of status or lawful status?

I would be great if anyone can provide insight on the above question.
