Looking at the map of results from the 2016 election in Indiana (where I went to college), the state was solidly pro-Trump but you can easily spot the blue counties where IU Bloomington (Monroe) and Notre Dame (St Joseph) are located. The only other counties where Hillary won are Marion (Indianapolis) and Lake (basically a suburb of Chicago). Tippecanoe county (Purdue Univ) is pink and went for Trump with 49%.
This indicates that even in a "red state", the university towns with lots of international students are already voting left and hurting them with this policy probably wouldn't affect the outcome of the next election.
