Applications are due on November 1 of the year preceding matriculation. Fluency in German is a prerequisite. Other graduate exchanges and graduate opportunities exist at the department or college level. For instance, The College of Engineering exchanges students with the Ecole Polytechnique F minine in Paris. Check with your departmental advisor for information on possible departmental exchanges.
Tuition is often minimal, and the choice of institutions and locations is broad.
Of course, students must speak the language of the country. Unfortunately, application procedures can be complicated, time-consuming, and confusing. In some countries, visa applications are an additional difficulty. At least a year's lead time should be allowed for direct enrollment. Students who apply directly to foreign institutions for study or research privileges should be prepared to handle the many details of a year abroad on their own.
