It is very hard to transfer direct from an int’l institution. Most int’ls come from a CCC. 2014 UCLA transfer stats:
Direct from Intl institution:
206 applied
11 admitted
Admit: 5.34%
Intl from CCC:
3,019 applied
793 admitted
Admit: 26%
I believe Berkeley and UCLA are the most transfer-friendly. These stats are from UCLA.
