Question about SIRing and Appeals

<p>I am going to SIR to a school I got accepted to (UC berk)
I also appealed to two other schools (UCI and UC davis.)
UCI and davis say that I would hear back in 3-6 weeks, so im betting I would hear back after may 1st.
So does this mean that I also have to sir to uci and/or Davis if I want to go there? Would it be like a chance thing? Or do I not have to pay/sir until I hear I got accepted (assume that i do) from them (and subsequently lose my sir payment from UC berk)?</p>
