Northeastern has a combined BS in Computer Science/Business. It may not qualify as a full business degree though. NU says that graduates “complete most of the requirements of a business major”, but they don’t appear to get a qualification from the Business School.

USC has a BS in Computer Science and Business Administration (CSBA). It may not qualify as a full CS degree though. USC’s plain-vanilla CS degree has ABET accreditation, but the CSBA degree apparently does not.

It is difficult to combine a full traditional engineering or CS degree and a full traditional business degree into a 4-year program. So sometimes 4-year dual programs may be “watered down” in one (or both) respects. This is a situation where professional accreditation may be helpful. The Lehigh CSB degree, for example, can claim both ABET and AACSB accreditation, which will generally convince skeptics that it is a “real” CS degree and a “real” business degree.
