Here in Kenya there was such a program in the 60's and was known as the "Kennedy Airlift".One of the earliest beneficiaries was Barrack Obama's dad. The other notable beneficiary was the 2004 Nobel Peace Prize winner Prof. Wangari Maathai. The program seems to have petered out after the end of the cold war.
Many of those whose studied under the program came back to Kenya when the country needed them most.
