Presidential candidate Donald Trump has said that he plans to get rid of a visa program that is estimated to bring in 300,000 student workers each year. The State Department says that this program allows for "cultural exchange" and brings workers with specialized skills to U.S. employers. It has been reported that despite the fact that Trump speaks out against it, he employs workers from this program at his hotel in Chicago. Trump still maintains that this program is bad for workers.
