Penn received a record high 40,394 applications for the Class of 2021

Assuming that 12% of admits are international, admitted number of international students would be 444 and the admit rate for internationals would be 5.7%…

The admit rate of domestic applicants (14.5%) is 2.5 times higher than that of the international applicants.

It is more or less the same picture in the other top schools.
