This is my opinion, take it as it is:

MBA, especially for foreign students, is worth its salt only if it is from Top 10 schools.  If you graduate from, say... UPenn's Wharton, then you probably won't have to worry much about your visa status or the recession.  However, if your "Yum Bee Yay" is from some obscure university in, say Oklahoma (nothing against OK, I'm just using it as an example), then you are in for some hard time.

Sagun05, if I were you, I would go for MBA school, provided, as I said above, it is in Top 10 school.  You can check various MBA ratings such as Business Week's annual survey to find which 10 schools are at the top.  Recession should not matter to you because by the time you finish your MBA, we should be well into economic recovery.
