If your planned project is a compulsory internship, it is best to contact the internship officer in your department. This person will confirm that the internship abroad will be credited to you at a later date. If it is a voluntary internship, you can contact a professor in your department with whom you have already attended a course, for example, regarding the learning agreement and the signature. The aim here is to have the content of the internship confirmed as being related to your studies.
