In Rihanna's scholarship program, citizens of Brazil, Barbados, Cuba, Haiti, Grenada, Guyana and Jamaica can receive between $5,000 and $50,000 per year to attend university in the United States.
From a May, 2016 article on NPR's The Record:
According to the terms of the program, each selected first-year student will receive between $5,000 and $50,000, and the awards may be renewed until each grantee earns a bachelor's degree.
Rihanna's Clara Lionel Foundation, a nonprofit she founded in 2012 that "works to improve the quality of life for communities globally in the areas of health, education, arts and culture," is managing the program.
