There is now a variable called "Fall Term International Students" for every school in the database. On institutional profiles, the variable is in the "Students" section under the heading "Total Undergraduate Enrollment."
International students are not eligible for federal Pell Grants, Stafford Loans, PLUS loans, or work study programs. Researchers may want to subtract the number of international students from the overall enrollment number before calculating the percentage of students who receive Pell Grants or other federal financial aid. One reason we added this variable was to make that calculation possible.
How do international students fund their US education? Possible sources include a student's home country, the US institution they attend, and international organizations such as the Fulbright program, the United Nations, and the World Health Organization. There is no centralized source of data on the incomes of international students in the US.
