At 1 p.m. on certain Saturday afternoons, hundreds of foreign-born professionals from all over the US converge on a small city in central Pennsylvania. They assemble in a high-rise office building, where they sit through four hours of college classes. Then they return to the airport and head home. 

What’s drawing these students to Harrisburg University of Science and Technology is not the prospect of landing a good job. A majority already have one. Nor is it the prestige of a Harrisburg degree. If they’re lucky, they won’t ever graduate.
