@eppixx,
I should have mentioned Finance. It could make a good major. I never heard of Accounting Information System as a field. Accounting IS an information system.
Whatever you choose, there will be some accounting and business management courses common to all, and majors can be changed. One point I was trying to make was that as a practical matter, some fields are going to require a master's degree. If you can't make that commitment, that might help by eliminating a few majors from the beginning.
