Best Summer 2018 internships for students interested in Political Science, Economics, and Business?

I waited until around February/March to look for internships this year which was a big mistake, so I’m starting to look earlier this year. I am a rising high school junior interested in Political Science, Economics, and Business and was wondering if you guys knew about any good internships in those subjects whether it be in NYC, DC, or anywhere else in the world. I’m just looking for very good and prestigious programs as I have incredible stats and very good ECs as well as a very high position in a humanitarian-related non-profit. One example of what I’m looking for is the UN Temple of Understanding Internship which I wish I would have applied to sooner last year.
Cheers!

You could look at think tanks, which are heavily based in DC, such as Brookings, Cato Institute, Council on Foreign Relations, Center for American Progress. You could also apply to the White House internship (don’t know your political stance), or since you have worked in humanitarian effort the Human Rights Watch ngo.
