I know like 60 a year go to Oxbridge for undergraduate. How many are admitted but choose US or other schools? In the UK, since you can only apply to Oxford or Cambridge, I would assume almost everyone admitted attends.
I don’t have a breakdown for just US applicants but 85% of international students who get offers ‘firm’ them, and about 12% of those don’t end up enrolling (presumably some got better offers and some didn’t meet their conditions). About 10% of US/US domiciled applicants get offers, the same as the average for all international applicants. As a side note, the 60 is almost evenly divided between US nationals and other nationalities who live in the US.
Some might also have difficulties with finances or visas.
