this is misleading. many top 10 schools make it clear that they consider applicants with mba degree abroad, or even mba degree in usa. LZ should check with every program you are interested in for confirmation.
that doesn't make sense...it all depends on how you justify yourself.
to Chinese applicants, we need to change our mentality a little bit. there isn't an absolute "can or can't", "yes or no" in terms of MBA application; everything's possible, and there indeed are too many special cases. What you really need is to convince the others why you are special.
