Change of Employer, H4 EAD Filing using Old Employer's I140

[spratt]

Hello Guys,

I have my I-140 Approved on May 1st from Company A. Now, i got an offer from company B. We are yet to start to start H1b Transfer process. Recently we filed H4 to F1 conversion for my wife, which is in progress. So far, I never applied H4 EAD for her. Question is

- If due to some weird reason, her H4 COS to F1 was denied and i already switched to Company B, Can i use my Company A I140 to get her an H4 EAD?

Thanks in Advance!
