International Relations and Politics

I am going to be a senior in High School, soon to be applying to a University. I already have some good universities in mind, I plan to major in International Relations with possibly a minor in Economics, Or I might double major with Political Science.

However, I when I get into College what are some ways I can get known in politics.

I know volunteering for a local congressional campaign, for example, is a good idea.

Thanks you.
