UDE's course database labels the ISE programmes "Bilingual". The ISE programme page states the split: half the lectures in German, half in English. English is required to apply, German is required at enrolment and B2 German is the admission requirement for the German-taught modules, so the degree cannot be completed in English alone.

Standing annual application periods for applicants from non-EU countries published by UDE's admissions office (Einschreibungswesen); the page prints day and month, not the year. The International Office's older page (last modified 2025-09-19) gives later dates for programmes without admission restrictions (15 September for the winter and 15 March for the summer semester); the admissions office page is newer and runs the procedure, so its dates are recorded. Applicants who need a visa should apply as early as the period allows.
