H4 EAD to Expired H1

Hello,

currently my wife is working on H4 EAD.

She was on H1 visa that was expired in 2017 with employer A. She moved to employer B with H4EAD. that is valid until 2019.

With all the immigration reform she would like to go back to H1.

  1. Can she use expired 2017 H1 with employer A to file CAP exempt H1 petition with employer B?

  2. if point 1 is not possible what are the other options to go back to H1.

appreciate your advise.

Thanks,

Joe.
