Threat to I-140 or Green card after employer change??

[care_candidate]

After receiving EAD after 180 days of pending I-485 application (Employment based) a candidate changes job from employer A to employer B. Can her employer A revoke I-140? OR is there any way that employer A can stop Green card application process?

This is legitimate application of direct employment with no consultancy and straightforward case of (F1 > H1b > PERM > I-140 > I-485 & I-765)

1. Revoke, Yes. That has no effect on the candidate.

2. Stop. No

The person is still entitled to change jobs in the same field once the AOS is pending 180 plus days.

I didn't understand your response.

Do you mean that employer A can revoke her I-140 and still after that it wouldn't affect candidate in getting her green card. What is the purpose of revoking then?
