This paper attempted to assess the  attitudes of students in the use of national and international languages in DRC and to identify the  factors that constitute  linguistic barriers  among Congolese students from three universities (UNIKIN, UPC, and Bel Campus). The study used  a quantitative method for data collection through a questionnaire given to each randomly selected representative sample of students, targeting only three faculties (arts, economics, and medical school). According to the survey results, the majority of students, primarily girls, were opposed to the use of local languages in favor of foreign languages such as French and English and also parents' social status has a significant influence on the use of the preferred language(s) of student targeted.
