Priority date loss upon revocation of I-140

Question details

1) Is there any difference between I-140 revoked by employer - vs - I-140 revoked by USCIS (say for fraud or misrepresentation) with respect to being able to retain the priority date with the new employer ?<br>
2) Changing from Employer A to Employer B - If Employer B files the PERM before I-140 by employer A is revoked by the employer A - would that help retain the PD corresponding I-140 to employer A ? In other words, are there any specific scenarios in this case - where the PD could be retained based on the first I-140 approval ?

ANSWER

As far as we know, USCIS has once again revered its position and has stated that priority dates will be retained if the revocation is based upon an employer's request.  See: the blog entry here
