According to an article on [1] msnbc.com, a  “New York teenager, who emigrated from Poland only five years ago, applied to seven Ivy League schools — and was accepted by every one of them.”

Great story.  However, imagine the geniuses of similar caliber who study at these great US Universities and end up returning to their home countries rather than benefitting the US.  Not because they “used us” but rather because the US won’t allow them to stay due to the lack of available H-1B visas or other viable immigration options.
