Hello, if I get bachelors Business Management or Economics, then minor in International Studies..?

Actually, I'm an international studies major. As far as I know, it actually is a very profitable major. It might be more government style focused but it does go places. I know a lot of kids at my school end up working at like the UN and stuff. However, I'm also a firm believer in double majors. They aren't as hard as some people make them out to be. It is an option for you. You might also look into seeing if the university you are planning has some sort of international business major that mixes the two. Otherwise, the minor would definitely help or maybe even a dual concentration of the two.
