Universities abroad are totally overrated. How are you going to deal with all the expenses? Even the people that have lived in first world countries all their lives suffer from student loans. How can you expect yourself to study in the best university in the world by joining signature campaigns?
Not to be optimistic but to be realistic, just study near your place. You might have a not-so-great college there, but I'm sure that when it comes to getting the job done, it's all about your skills and experience. Sure, great college has all those necessary equipment and laboratory materials, but it all depends on you.
