It takes anywhere between a month to 4 months to see the IL after FP. You can join this thread while waiting for your IL

LUD changes once after FP notice was issued and again after interview was scheduled (case transfer to local DO). There won't be any LUD updates otherwise. You need to wait until your interview was scheduled. That takes anywhere between a month to 4 months on average.
