Is the USC SIR binding?

<p>Hello Everyone! I just sent in my SIR to USC because of the fact that the deadline is tomorrow. However, I just received my financial aid for another school and wish to go there instead (not that i wouldn't love to be a trojan). How do I go about doing this? Is this possible? Thank you everyone.</p>

<p>Just let USC know you have decided not to attend - call or send a letter. The deposit will not be refunded, however.</p>

<p>Good luck!</p>
