You can indicate your interest in studying at DIS for the full year prior to the start of your semester, or seek to extend once you are here. You can switch locations between semesters from Copenhagen to/from Stockholm at the same cost. Read more about extending your stay between semesters here.
Or, if you are a spring semester student, why not stay for a summer session in Copenhagen or Stockholm, or mix and match between up to three sessions! Read more about extending to stay for the summer at DIS.
