The article is a year old, but still applicable. Here is a link to interesting article on the advanced degree exception to the H1B cap. This year 20,000 seats were reserved for advanced degree holders from American public (or non-profit) universities. Sorry University of Phoenix grads!
The exception was meant to help keep the most talented foreign grads, but if often doesn’t work. There aren’t enough seats and one has to ask the question of whether any weight should be given to the quality of the school. Should a Harvard MBA count for more than a University of Western Wyoming MBA for immigration purposess.
