Hudson Valley Community College, a SUNY associated two-year college, is located in Troy in Rensselaer County, New York. Although about eighty percent of the students are from the local area, the remainder are from other parts of New York, other states and from some 30 countries around the world.
There are students who come from at least 30 different US states enrolled at Hudson Valley Community College
The context says that there are students from other states but does not specify how many states are represented in the student body. I think the system was confused because the context mentions that there are students from 30 different countries.
