Changing Job on H1B or EAD? which one is safe?

[SaiDivya]

Hello Experts,

Please help me to advise in this scenario:

My PD is 01/2013, EB3 straight.
Receive Data : 10/2019
EAD : approved
medicals : waiting for RFE
i-485 - pending

I did my GC filing through the employer A. I got another job opportunity with employer B (similar job).
Employer B applied for H1B transfer. By the time H1 got approved, I did receive my EAD approval too.

1. Since my I-485 is still pending with USCIS, which is safest way to join with new employer B now - H1B or EAD?
2. Is porting needed if switch to employer B on H1B?
3. Is porting needed if switch to employer B on EAD ?
4. If I switch to the employer B, what kind of issues can be possible with employer A? i.e. any withdrawals, revokes can happen?
5. What kind documentation is needed from employer B other than i-485-J?

hi,

I am also looking for these answers. Were you able to get any information?

What I heard is if your EAD is pending for more than 180 days you can change employer. But i am not sure if the job should match with PERM that was filed.

Thanks.
