ABSTRACT
A substantial number of highly skilled people from the Third World also entered the United States as a result of the passage of a new immigration act in 1965 that placed emphasis on US skilled manpower needs and upon the skills and educational levels of potential immigrants. Since World War II the world has witnessed a major shift in international migration, as people have migrated from the low-income countries of the developing world to the more developed industrial countries. One pattern of migration was from the colonies to the former imperial powers as a consequence of decolonization. In addition to Third World migrations to North America and Western Europe, substantial migrations into the oil-rich countries of the Middle East have occurred. These labor-short countries imported managers, technicians, teachers, and workers for construction and manufacturing and for their expanding service sector from other Arab states and from South and East Asia.
