Nothing. We did not send ours out until late October (even though we married in the middle of May). His AOS was approved without an interview in a record breaking two months! However, it would be best to do it ASAP so he can sooner get work authorization and get a job!
I just caught my error! We did not send out AOS out until late JULY. So, more than two months after getting married and well past the 90 days since he first arrived to the US.
