Change the employer while green card in process

[niku4u]

Employer A applies my green card now. If I get better offer later can I switch to another employer B and carry the employer A green card application/priorty date with me for employer B?

You can retain the PD of an approved I-140 when a subsequent employer files for your GC...PERM...I-140 etc. At the filing of the new I-140 you can retain the previous PD which would be the date the previous PERM was filed.
