Hi staaram,
Well, I deleted the posts because I felt bad for my lawyer
...but a fellow forum member sent me this:
(e) Retention of section 203(b)(1), (2), or (3) priority date. A petition
approved on behalf of an alien under sections 203(b)(1), (2), or (3) of the
Act accords the alien the priority date of the approved petition for any sub-
sequently filed petition for any classification under sections 203(b)(1), (2), or
(3) of the Act for which the alien may qualify. In the event that the alien is
the beneficiary of multiple petitions under sections 203(b)(1), (2), or (3) of
the Act for which the alien may qualify. the alien shall be entitled to the ear-
liest priority date. A petition revoked under sections 204(e) or 205 of the
Act will not confer a priority date, nor will any priority date be established as
a result of a denied petition. A priority date is not transferable to another
alien
I believe that once you have your first i-140 approved, your employer can file a second perm and i-140, and once that is approved, when filing for i-485, you can recapture your initial priority date by indicating it on a cover letter and refering to the regulation in the letter as well. The other members know much more than I do about the topic. Perhaps you can consult with them or an attorney.
Good luck.
