UCI, UCSB, UCLA Appeals? What comes after?

Does anyone know when the specifics are for each school? I’m basically an addict at this point and check obsessively. I was really hoping to get into one of these UCs and kind’ve feel at lost with the world right now. I know they all have very general deadlines and approximations: “after May 1st,” “4-6 weeks,” “by June 30,” so I’m just wondering does anyone have some new info on potential release dates, when to expect rejection again, etc?

On another note, I’m currently lost on how the system views me if I happen to get accepted. How will the SIR work, since I’m expected to submit to another school within the next 4 days? Does my financial aid still qualify even as an appeal applicant? Am I no longer guaranteed housing?
