My daughter did PPE in Oxford. Graduated two years ago. Found a good job in UK in consulting and currently lives in London. She has a British boyfriend and tons of British friends from college. She also has pre-settled status so this takes care of the visa issues.
IMO, if the goal is finding work in US, it’s better to study here. The uk college system is very different and the adjustment is not easy. It’s difficult to get a first in a humanities field (if grad school is the goal). My d got the equivalent of a first in the economics courses but did less well in the politics courses. She is very happy there and does not want to come back
