I140 Priority date

I have a I140 priority date for March 2017. I’m planning to go on a different visa or may be leave USA altogether for a few years. Can I come back on H1b visa a few years later and use my priority date (hopefully close to current date) to get a green card?

Yes you can provided your GC sponsoring employer still has the GC job for you and is able to pay you per the LC/PERM.

Appreciate it. Thanks for replying.
