H1B transfer when I-140 approved and spouse wants to be on H4 EAD and

I am on H1B right now and my I 140 is approved. If I change my employer now how would it effect my wife work life (If the proposed rule becomes law for H4EAD) ? I heard that the current date would remain unchanged but I-140 has to be approved again. In that case , do you think they would allow the H4 to work in IT sector?

in same boat. what will happen once they get EAD and we change jobs?

In your question, current date = priority date of your immigration petition.

At any time, if you dont have a valid i140, the underlying H4EAD of your spouse is invalid. She needs to apply for her EAD once you get a valid i140 approved with the new employer.

Your priority date would be attached to your alien number(which would be issued only up on your i140 approval).

With EAD, any one can work on any job(even selling flowers at the street corners also allowed) in USA
