„Countries implementing stricter entry rules must also take into account the growing importance of tuition fees from international students as a source of university funding, as well as the fact that international graduates constitute an important talent pool to help address skills shortages. Some OECD countries thus tend to focus more on selective criteria for attracting international students and on measures to retain them and facilitate their integration into the labour market.“
