Probably they chose schools that don't require GRE or low GRE scores. I don't think these 950 plus a$$holes went to IVY leagues or even unranked decent schools. They probably got admits in schools like International American University or United States University or International Technological University. When I was in Texas, I used to see lot of apartments in the Irving and Richardson area where 12 plus Indian guys and girls staying in a 2 bedroom apartments claiming to be Students. When you talk to them, you will learn that they faked their way to US. No surprise where they come from as most of them hail from that one state (which is divided as two now).
@PRANIT01 and other Indian here probably knows which state(s) I am talking about. They attend namesake colleges for 4 to 6 times in a semester and give exams. Rest of the semester they work at Desi Consultancies (Indian IT Sweatshops) doing coding or marketing work and few work at Gas stations and Restaurants. I did speak to few who are brilliant (In coding) but they come from poor families and this is the only way for them to comes to US. USCIS knows this and they don't give a two f about it.
