After job changes does it require to start PERM process again ?

[MindPower]

1. Employer A filed I-140 for me and got approved now for more than 180 days and also not revoked. Now I changed my employer to employer B. Is it      required to start PERM process again with new employer ?

2.a. If yes then what is reason to start PERM again ?

2.b. Is it worth taking risk to start PERM process now since there is a lot of turmoil going on in H1B world ?

3. if no then what will be the impact on I-485 whenever date will become in future ?

PERM is employer specific. Why do you think A will employ you later on?

[MindPower]

Is there any alternative if A denies to provide Supplement J at the time of filing I-485 ?

Will AC21 be useful in this case by any chance ?

PERM and I-140 are employer-specific. A new employer would have to start the process from scratch.

You can reuse the PD of an earlier approved I-140, and the H1 can be extended past the 6 years. That's it.
