EB3 / EB2 and Masters question

[dileepsv]

Hello there,

I currently hold a BS Engineering from Canada and am employed in the US.
Thinking of starting my TN to GC application with my current employer under EB3.

I have the following questions regarding this :

1) Is it necessary to have a masters in engineering from a US university in order to qualify for EB2 ? For example, what if I pursue this MS/Meng from Canada and find a job that requires a masters degree ?

2) As I understand, the EB2 to EB3 porting can be performed under the same priority date that was obtained initially with the EB3, correct ?

I really just wanted to understand if the Masters in US or Canada makes a difference on these EB3 to EB2 porting applications -- anyone with input / advice on how to proceed ?

Tuition is almost half in Canada

Thanks a lot !

1) You need a "U.S. Master’s or doctoral degree or its foreign equivalent" so I suppose an accredited Canadian school would do

2) You can port priority dates to a new EB petition in a different EB category, as long as the underlying petition was not revoked by USCIS itself for fraud/misrep
