I was accepted to UCSB on 1/23, but noticed they had been intermittently doling out acceptances for several weeks prior. I think it's certainly still possible to be accepted, but they only have two visitation weekends, which require RSVPs by 2/6 or 2/26. Given that the first RSVP deadline has already passed, I'm willing to bet that they haven't sent out rejections yet because they are "waitlisting" students until accepted students start to decline their offers, and intend to fill holes accordingly. Unfortunately, this may mean that you won't get to visit on their expense.
