Just signed my SIR and made the deposit, when will I have access to my USC and be assigned housing?

I’ve already was able to apply for housing after making the deposit, but right now I’m trying to activate my.usc.edu account and the system is telling me that it cannot find my USC ID. Does anyone know how long it will take before I can create my my.usc.edu account (which is necessary for signing up for orientation)? I was also wondering if anyone knew when us transfer students could expect to hear back from housing, if it all (since I know we are pretty late having just been accepted).

Thanks all, I’ve got so much to plan in such small amount of time!
