Are SIR decisions permanent?

<p>I was just declining my acceptance to UCI and I noticed that the website kept saying that if I changed my mind I could always go back and say yes. Does every school do this? It’d make me feel a lot better to know I could always go back and say yes if something came up. And I don’t want to check if they’re permanent myself in case they are :P</p>

<p>I would assume that as long as the deadline hasn’t passed yet, you can change your mind. But once you’ve payed that deposit money, that money’s gone.</p>
