Georgetown majors

Hi! I am a current high school senior and will be applying to Georgetown. I am trying to decide which school to apply to, as I know you cannot double major across schools. I am interested in lobbying and investment banking; however, although this is a difficult and almost unattainable career, I think being an ambassador is very interesting as well.
Here are the majors I’m considering in each school:
College–economics, government, political economy
SFS–international economics, international politics, international political economy
Business–finance, international political economy and business

Any insight you have to offer would be greatly appreciated! I absolutely love the school, and I am definitely applying. Thanks!
