Questions on keeping priority date

[jsteak]

Hello H1 Gurus,

My Background:
My LC and I-140 were approved.
I'm not able to submit I-485 because my priority date is not current.
I’m now considering changing job.

My questions:
1. Can I keep my priority date?
2. If I can keep the priority date, to let my future employer process my Green Card application with the old priority date, what kind of the proof is needed? Either from me or from my former (current) employer?
3. Has anyone has similar experience?

You need to have an approved copy of I-140. With this you can move to a new company file new PERM and at the time fo filing new I-140 apply for your old PD, by sumitting the copy of your old approved I-140. You will be given that old PD provided your old employer does not revoke/NOID your old I-140 application. In that case you will loose your PD.
