The completion of a mobility period at UPB by a student from another HEI requires the existence of a bilateral agreement between the two institutions and the definition of an individual study contract for each student on mobility. The individual study contract establishes the curricular units that the student will attend during their mobility period at UPB. In Portugal, the first semester generally begins in September and the second semester in March. The study contract is drawn up between the student and the institutional offices of the two institutions. Students interested in a period of mobility at UPB should contact the office responsible for this program at their home institution.
