Where should a talented 20 year-old developer go?

All my life I've wanted to work in Silicon Valley and after reading this post -- https://news.ycombinator.com/item?id=9764564 -- a few days ago it seems like I might not be able to. I'm in the middle of a bachelor's degree in Computer Science from a well-respected state school on an F-1 visa and was wondering where I should go after graduation.

Europe? Canada? Try to fight it out in America? Thoughts?
