In this article, we report the findings of an empirical study in which we explored how the internationalisation of academic staff informs the global citizenship (GC) of graduate students at Makerere University in Uganda.We were prompted to undertake the study by the seemingly low levels of GC among university graduates in Uganda. We collected data from seven purposively selected graduate students using semi-structured interviews,which were triangulated by reviewing an assortment of university documents. These data were analysed inductively using the thematic content analysis technique. Our findings revealed, among others, that internationalstaff on the academic team, global perspectives, respect for diversity, andadequate and proper use of information and communication technologies(ICTs) by the academic team were effective in fostering global knowledge, self-awareness, empathy, awareness of responsibility, and a broader viewof the world among graduate students. These findings reinforce the belief that the more internationalised a university’s academic staff are, the more global its graduate students will become. Thus, significant efforts need to be made to internationalise academic staff, and other aspects of university operations. This work presents to university management aspects of Internationalisation of academic staff (IoAS) that greatly impinge on the GC of graduate students. No earlier works had similar results in the context of the global south where IoHE has not yet taken root.
