<p>So what happens if we submit the SIR at UCLA and also accept the offer of some other college like UT-Austin or UW-Madison and then decide to go there instead of UCLA? And what if we decide to go to UCLA, what then? Do we email them that we're not coming or are we not allowed to do that?</p>
<p>And what if we've been waitlisted at a place and have already submitted the SIR. If we get into the place where we've been waitlisted?</p>
<p>Can we do this and later email UCLA and tell then we're not coming?</p>
<p>It would be really helpful if someone who has done this explain the whole thing.</p>
