change address while 485 pending

Just moved to new address. Asked company lawyer, they said just file a AR-11. is this all? Would nebraska(where my 485 is processed) get notified when this ar11 is sending to somewhere in Kent?

I checked USCIS website, they said 2 steps are needed, firt step is file ar-11, 2nd step is to notify uscis when one case is pending, in my case is 485. but they didn't say how to do step 2?


thanks
