Ok, this is just disconnected from reality. Most people in the US haven’t heard of Caltech, let alone a foreign university. Maybe Oxford, but that’s not at all certain. The average person knows Harvard and MIT because they’re in movies, whatever big school is closest to them, and a some sports schools.
Sorbonne is #48 in the US News global rankings. Pretty good! But well behind the weakly known Caltech (#9) or the top ranked Harvard (#1). The next highest rated US school above Sorbonne is the University of Pittsburgh. No one would ever say “just swap your Harvard degree for Pitt, it’ll open similar doors”. And this is on a list that’s largely judged by people in academia who have a wide familiarity with schools. Ask a random American whether Utrecht University (#44) is a good school and they’ll have no idea. They’re unlikely to even known Utrecht is a city.
