A good friend of mine had to make the same decision two years ago. She was planning to go to OSHU, but then got into UCI off the waitlist in late July. She was originally really excited about OSHU, but the opportunity to save lots of money, and in her case, to be near family, won out and she chose UCI. I think the money is really a big deal, which no one has mentioned so far. OSHU isn't cheap. My friend is very happy at UCI and doesn't regret her choice.
