<p>Hey CC!</p>
<p>'If I accept an SIR (statement of intent to register), do I have to decline other colleges' offers IMMEDIATELY? How long do I have to decline their offers?</p>
<p>Thanks!</p>
<p>It would be the polite thing to do. You can wait until you receive any financial aid offers so that you are positive that you will be going to the SIR school.</p>
<p>It would be nice to decline the other offers once you made the decision, so they can make arrangement for the candidates on the waitlist sooner. </p>
