Bachelor's degree course: A stay abroad from the 5th semester onwards makes sense. Master's degree course: A stay abroad is possible at any time. The ERASMUS programme of the TU BS offers various exchange opportunities with European universities, e.g. in Logrono, London, Linköping or on La Réunion. With the ISEP programme students apply for stays at non-European universities. Master's students with business degrees can apply for one-year residencies at the University of Omaha and University of Rhode Island with the opportunity to earn an MBA.
