should job title match for I140 Porting?

[techluver07]

1.If I want to port I-140 PD from company A(EB3) to company B(EB2),

Should both job description match? or PD porting can be done any job title in the new company?

2. Lets My GC process in progress(I140 approved), If I get promotion with job title change(associate to senior associate or associate director or director etc),Will I have to start new GC process because of promotion & job title change?

For your first question:

Jobs descriptions need not match to retain your PD.
