Here is how to understand what happened with the ICE fake university
ICE recruited hundreds of these students to Farmington and then arrested them for violating the terms of their visas, which mandate that they be enrolled full-time at a federally accredited educational institution while they complete their studies. The tricky part is that it is unclear why the students were enrolling in Farmington instead of a legitimate university.
According to Matt Friedman, who worked in the same complex, the university had no classrooms and he never saw anyone there.  Other people who work in the same building doubted the prosecutors’ version of everybody being willfully involved and asserted to have seen students arriving with backpacks and inquiring about the university, but struggling for any resolution. 
Ravi Mannam, an immigration lawyer based in Atlanta, criticized the operation as “misleading” and accused the government of utilizing “very questionable and troubling methods to get these foreign students to join the institution”, since some students were under the impression that their enrollment was being made in a legitimate program.   Similar concerns have been echoed from various Indian news publications.   
The Immigration and Customs Enforcement (ICE) has come out clear on setting up a fake university that it said was necessary to understand the pay-to-stay scheme and abuse of nonimmigrant student visa system in the United States.
The fake school was set up by the Department of Homeland Security in 2015 as part of a sting operation to bust foreigners fraudulently enrolling in U.S. schools for visa purposes, as well as recruiters profiting off of registering students in these fake programs.
Emily Neumann, an immigration lawyer based in Houston, has advised anywhere between 25 to 50 students, in most cases giving them informal advice on how to voluntarily depart the country. She said the story of nearly every student she advised is the same: the students attended master’s programs in the U.S., then started working through the OPT program. They applied for an H-1B skilled worker visa to extend their stay beyond the one- to three-year period provided by OPT. But their application either wasn’t selected via the lottery or was denied for some reason.
That said, North suggested law resources could be used to crack down on actual colleges that might be questionable. “One of the things that they might do at considerable less expense is grit their teeth and go after the marginal ones,” North said.
The remaining 10% “have either filed for some sort of relief or are contesting their removals with Executive Office for Immigration Review,” said HSI Detroit.
Assistant U.S. Attorney Baker said in court that Rampeesa was “aware it was completely fake,” that “it was just for maintaining status.”
