You can look at each school’s common data set (CDS), section D, to see transfer admissions data.
Note that some top colleges have agreements with local Community Colleges, so those students have preference over others. Some schools may look like they accept many transfers, but in reality the acceptance rate is lower for students not coming from the CCs…schools like Cornell, UCs, and some other top state schools (UVA, U Mich) are examples.
