as of yet, ucla is pretty oos unfriendly (though, it's also not very friendly to instaters). they tend to be very picky with their interviews, but an interview from them is VERY good. like if you dont pull down your pants they'll take you -- they really dont waste time interviewing people they arent prepared to accept (i'm willing to bet of the stats posted above most of those people got into UCLA that interviewed, but some of them went elsewhere to SF or harvard or some other crazy place)
it should be interesting to see if the tides start to change. i know UCLA undergrad is trying to recruit more OOS/International (all the UC's really) so they can help with the budjet crisis but if that transfers to the professional schools, only time will tell.
if you dont have like 23AA though, OOS is a long shot.
