adopt a student perspective in order to explore the notion of a multilingual university in the bilingual territories of Catalonia, Wales and the Basque Autonomous Community (BAC). This also includes looking at how the students view the relationship and possible tensions between internationalisation (and its concomitant student mobility) and the language policies. In order to investigate the attitudes and beliefs of the students (both home and international) in connection with the notion of a multilingual university, we asked them to complete an open-ended questionnaire item regarding the advantages and disadvantages they see in such an institution. The results of the analysis point, in the first place, to different perceptions among students of a multilingual university depending on (i) whether English is the main or even sole means of instruction, and on (ii) the perceived status of the minority language. Secondly, the analysis suggests the need to approach students’ attitudes towards a multilingual university by considering the ways in which the sociolinguistic context (in official, academic and experiential terms) may have an impact on their perception of the process of multilingualisation in universities.
