Dear Sir/Madam,

I have 12 years of experience in IT industry and I 140 approved in EB3 category.
Since, I have only 3 years degree (BSc. Physics) from India, I am perusing postgraduate diploma in IT management from Universitas 21 http://www.u21global.edu.sg/Education/About/Ac...). I found they are quality education provider but not aacsb accredited.
So after completing postgraduate diploma, can I upgrade my GC to EB2 category assuming I will get a job/promotion which can allow me to file in EB2? U21 have tie up with university of Virginia, Melbourne, Nottingham, Birmingham and their logos will be displayed in the certificate.

I can opt for getting degree from Uni. of Melbourne instead of U21. If this makes sense?

And diploma sufficient or I needed to do masters?
