Here’s some more for you:
“Most of the international students pay for their American education, which is the most expensive in the world, with personal or family funds. About 20 percent receive funding from their respective American institution, while a smaller percentage receives funding from colleges or governments in their home countries.”

Oh, and a bonus for you, re: federal work study:
“Generally, International or foreign students do not qualify for the Federal Work-Study program.”
