An exposure s a two-year learning pathway around a particular societal theme, involving an exchange between students from UAntwerpen and from one of USOS' partner universities. Each pathway consists of a digital component and an immersion component. Students from UAntwerpen and from the partner university go through the entire pathway together. Digital sessions take place during the academic year, while the immersion sessions continue during the summer.

Since its inception in 1985, USOS has organised a total of 77 exposure trips. For academic year 2022-23, students can apply for the exposure to Oujda in Morocco (summer 2023 - proficiency in French and Dutch is required) and for the internship in India, for Law and Social Sciences students writing their thesis the following year at University of Antwerp (proficiency in English required).
