UNESCO has published its 2019 Global Education Monitoring report with a special focus on migration and displacement in connection to education. Although the main focus is on involuntary migration and displacement (one in eight people on the planet has moved either within the country or internationally), the report has a special chapter on the mobility of students and professionals. One of the key messages is that recognition (for academic and professional purposes) is essential to maximize both individual and societal value of migrants.
Another key message is that internationalisation in higher education is getting more and more diverse, but employability remains a key driver of student mobility; this was shown i.a. when stricter visa regulations in the UK immediately were followed by massive reorientation of Indian students towards Australia.
