International development in the era of globalization needs an effective transfer of knowledge and human capital from the main centres of knowledge creation to developing countries for supporting their growth and development process. Most of the new knowledge is embodied in people. Developing countries create their qualified human resource base at home and developed countries ‘import’ technical expertise from abroad. This process has raised concern, particularly in developing countries. This process, however, needs not be irreversible as people tend to return to their home country bringing with them knowledge and experience thereby contributing to national development.
