Checked my email today as usual in the morning after coming to the lab and found my 485 got approved. My case history:
ted day of 140: May, 2005
Approved day of 140: Sept, 2005
ted day of 485: Spet, 2005 (with my wife)
Approved day of 485: May, 2007
It's weird though that my wife hasn't received the approved notice so far.
