Both Visiting Students and Associate Members may study at the graduate level either in cooperation with one of the primarily undergraduate colleges (which all have graduate students) or as a Visiting Student in one of three graduate colleges. WISC has had an arrangement with St. Antony's - the graduate college of International Relations - since 1987. Two other graduate colleges, Linacre and St. Cross, have also invited us to recommend Visiting Students. Such graduate students have studied Law, International Relations and Business in the past as well as Arts and Sciences. Every year, several WISC alumni return to Oxford to study as candidates for graduate degrees. Recommendations from their former Oxford tutors are usually helpful.
