Just spoke to IIO at NSC to inform change of my address. Also I asked them how long will it to process my 485 application. They told about 3 months from now and they are processing cases filed through 04/01. She mentioned since my ND is 07/19, it will take about 3 months. But I thought they process by RD.... My RD is 6/14 and ND is 07/19.
