Internationalization of higher education in theory is "the process of integrating an international, intercultural, or global dimension into the purpose, functions or delivery of postsecondary education."
Internationalization of higher education in practice is "the process of commercializing research and postsecondary education, and international competition for the recruitment of foreign students from wealthy and privileged countries in order to generate revenue, secure national profile, and build international reputation."
". The main components of internationalization of higher education are recruitment of international students, development of international branch campuses, students, staff and scholars exchange programs, internationalization of the curriculum, and research and education partnerships between institutions regionally and internationally. There are specific rationales which are driving the internationalisation and strategies which are being used in the internationalisation of the high education institutions (HEIs).
