Each department has specific reasons for requiring departmental approval on its courses. You must contact the Director of Undergraduate Studies (DUS) from that Department to obtain approval. Contact info is always listed on their departmental webpage. Advisors in the Mendoza College of Business can help you understand the restrictions on Class Search but have no jurisdiction over non-business courses.
Understand that for most major level courses, majors receive first priority! If there are seats open after all majors register, you may make a seat request. Major level business courses are handled by the individual departments:
ACCT: Prof. Colleen Creighton (ccreight@nd.edu)
FIN: Prof. Jim Leady (jleady@nd.edu)
ITAO: Prof. Jen Waddell (jwaddell@nd.edu)
