I need some help.

I am a junior in high school ATM but I'm looking to get a degree in international studies. It's never too early to start. The catch is I want to go to college in the UK, University of Warwick to be specific. Does anyone have any links to help me find information on scholarships for international students, student visas, etc. or just any advice in general for those of you that have done this?

If this is in the wrong subreddit please direct me to the right one. :)
