I140 change of jobs

[supig]

I am currently on a H1 B visa.

I have completed 6 years on my H1 B visa and currently it is being extended yearly.

My company has filed my I 140 and has received approval for the same.

 

 

1. Can I change companies at this point?

2. If yes, then what are the implications of the same w.r.t my priority date and I 140 validity.

1. Yes.

2. Employer might revoke approved I-140 and in that case you cannot retain PD.

@jairichi - You've mentioned in #2 that "2. Employer might revoke approved I-140 and in that case you cannot retain PD." 

 

Is this the case always? Or this decision depends on USCIS and they do sometimes retain the old PD? 

 

Could you please confirm? 

 

Thanks in advance!
