This article broadens the knowledge about the experience of academics in relation to how the internationalization of research has changed in a southern country and tensions that have risen depending on the different disciplines. This work resulted from interviews and documentary data collected mainly through semi-structured interviews with 57 administrators (including University rectors, provosts, vice-rectors and deans from multiple disciplines) who had been involved in developing the research strategies. Findings suggest that trends between disciplines differ notoriously. Publishing in foreign countries is more likely to happen to academics from hard sciences. Social sciences and humanities' research activities are often performed in books and book chapters. This translates into an initial disadvantage for social sciences in terms of internationalization since the result of their work is often less visible abroad than scientific indexed papers. This difference might be problematic if used as an indicator of academic productivity and recognition without considering disciplinary differences, especially in countries where research capacities and internationalization are still under development.
