That's an excellent question. In all the studies on factors that may attract students, the language question is obvious. It may prove difficult to study in one's second language. Students may have perfect mastery of another language without being comfortable enough to study a specific subject in it. There are many other factors, such as the quality of instruction, the supply of courses and the opportunity to take a specific program. We know that some programs are offered only at certain university institutions. The prestige of the institution often plays an important role, as does the institution's proximity and educational costs.
