International student mobility and the internationalisation of higher education receive increasing attention for some time already, especially since they relate to sensitive topics of public concern including education, migration and development. Migration for education is not a new phenomenon. However, the number of foreign students enrolled in tertiary education worldwide rose significantly during the past decades, from 0.8 million in 1975 to 4.6 million in 2015.
