I-140 porting - different job title and duties

[gbg]

Hi,

What are the rules around porting the priority date from i-140? Would I be able to port the date if the new I-140 is for a position with a different title and different job description. For eg: If my earlier i-140 was for a business analyst position, would I be able to port the dates for a new I-140 for a Product Marketing Manager. 

Is there a requirement for the new position to be same or similar?

 

Thanks
