Education internationalisation promotes intellectual capital migration whose goal is to gain equal access to quality education. The competition for highly qualified labour resources is intensifying from year to year. The high developed countries developed the mechanism for increasing the efficiency of the education system and the rapid integration of migrants into the country's multicultural environment, eliminating social, economic, and cultural barriers. The paper aims to analyse the modern education systems in the context of attracting intellectual capital to the country. To identify scientific patterns in research on the outlined issues, the authors conducted a biometric analysis of 804 scientific publications published in Journals indexed by the Scopus. VOSviewer and Scopus Tools Analysis tools are used for bibliometric analysis. The authors determine that the growth of publishing activity on the subject has occurred since 2000. The article identifies the TOP-10 countries and researchers by the number of publications devoted to the study of education and intellectual capital outflows for 1990-2020. The ratio of private and public universities among the studied countries showed that the share of public universities is higher in most countries. One of the criteria for selecting a destination country for educational migration is the education quality in the country. The authors analysed the rankings of countries on higher education quality according to the QS Higher Education System Strength Rankings and the Human Development Index in 2020. In order to compare countries in terms of intellectual capital outflows, the authors analysed the positions of countries in the Human Flight and Brain Drain Index. It is found that the leading countries in the education quality have smaller amounts of intellectual capital outflow. The points of attraction of the Human Flight and Brain Drain Index change in Ukraine were in 2014–2015, after which the value of this index began to decrease gradually. In 2018, the value of this index began to grow, which indicates an increase in brain drain from Ukraine. Given these trends, the Ukrainian government needs to study the experience of leading countries in reforming the education system to improve its quality and reduce the outflow of intellectual capital.
