I am not aware of any geographical constraints you might have but from what little I have seen, try picking up a good school either in Germany or Switzerland for your undergrad. Get a masters fellowship such as Erasmusmundus or DaaD, then move to Berkeley/Stanford for PhD…

Good schools in europe require you to be proficient in their native language.

It is usually worth the effort and would provide you with invaluable experiences…
