I have not yet decided whether I want to major in international business. All business majors share the same requirements for the university core curriculum and the additional college requirements. Other majors do not have a language, though they usually accept some non-business electives. Thus, if you plan well you can progress much of the way towards an IB major without losing credits if you change your mind. I noticed that you list some dual majors.
Dual majors share the same college requirements.
Dual degrees, however, generally are not worth the effort because it will usually cost too many extra credits to fulfill different lists of lower-division credits. You would be better off getting an undergraduate degree and then using the same time to get a second, different graduate degree.
