They came over here primarily for an education, right? If so, then the investigators need to pull their academic records and see exactly WHAT they’ve been studying and how much. Too many of these types get in on student visas, and the colleges/universities love it. They rake in more $$ for non-resident tuition and fees, they can spout off about a “diverse” enrollment and on and on. Most of not EVERY university in this country has a chapter of the Muslim Student Association (MSA). http://en.wikipedia.org/wiki/Muslim_Students%27_Association
