ICE created a fake university to entice foreign students, charge them money, and deport them. The students came legally on student visas, but since the school was fake the visas were invalid. (2019)
From the department of Justice (forgive the gendered language, it was written in 1973):
"THE ENTRAPMENT DEFENSE IS USED WHEN AN ACCUSED PERSON ALLEGES THAT HE NEVER WOULD HAVE COMMITTED A CRIME IF A LAW ENFORCEMENT OFFICER HAD NOT INSPIRED, INCITED, PERSUADED AND LURED HIM."
The university was set up in the same manner as one that holds accreditation and takes smaller fees than actual tuition would cost, so that immigrants can claim they are students for a fraudulent student visa. ICE claims that these students were obviously interested in this arrangement, and not a legitimate education, because the university didn't even have classes that students could sign up for and the students stayed enrolled. However, it is clearly entrapment as the university had been validated by the government publicly, and some students who were tricked into enrolling had later tried to transfer out to a real university, but were still arrested regardless.
