Strengthening America's Public Schools Through Promoting Foreign Investment Act - Amends the Immigration and Nationality Act to permit a lawful alien who enters the United States on a nonimmigrant student visa (including Mexican and Canadian commuter students) to attend a U.S. public secondary school for longer than one year if such alien reimburses the local educational agency for the full, unsubsidized per capita cost of providing education at such school for the period of the alien's attendance.
