Hi! I got accepted into the MIEF program as well!
I talked to a lot of people about SAIS and the MIEF program. All of them unanimously agree that SAIS is the best when it comes to job opportunities (WB and IMF being a stone throw away et all) and in terms of networking opportunities. The only bummer is that is that it's a one year course but the credit hours is the same as that as a two year course. So it's a good course choice and a very good university.
