Everything hinges on where you intend to live and work as an adult. If it's the US, and if you will have a green card (right to work in the US), then I would highly recommend that you do you college work in the US. If you want to become a professional pilot, I would recommend an university with an aviation program.
Here's a link to almost all the major universities in the US with aviation programs. One of the best is the University of North Dakota (of all places). Good luck.
