I, too, am waitlisted at Irvine LPS. I am in at UT Austin. For what it’s worth, UT has been transparent about their funding situation; they upped the first two years to 20k (so, not a ton, but not too different from many schools), and have additional funding opportunities down the road (e.g., if one teaches a class).
Irvine certainly seems like a standout in terms of placement- I would only choose a couple of schools over it for studying phil of science/logic (Pitt HPS, Princeton, Stanford). They also send people to good industry jobs. Have they given you any indication of the likelihood of admission? There are so few of us on the waitlist that I am hopeful.
