U.C not responding and SIR

So, I applied for 2 U.C. One of them accepted me and I gleefully paid the SIR for that U.C. The other U.C didn’t sent me a acceptance letter or a rejection letter yet, to this day. So I’m wondering what should I do ?
If I did get accepted to that U.C that didn’t send me anything and for some reason it only notify me on the myadmission website for the U.C, and I don’t pay my SIR, it would just decline my application, right ?

if you don’t send in a SIR by the deadline then they assume you aren’t coming. So if you don’t want the college that didn’t send you anything over the one that did, you need do nothing more.

Otherwise, go talk to your xfer counselor and see what they can find out. I’m assuming you are a xfer student since the frosh deadline was so long ago and xfer deadline is tomorrow.
