I got my green card late in 2005 and then moved residence in Jan 2006. The online change of address was not available then and so I sent in the AR-11 form with priority mail and confirmation delivery within 10 days of the move. Should I care if they actually updated my records then? This August I need to apply again to get a permanent GC (since my marriage was not 2 years old when I got my GC). Is there any likelihood that they will come back and say - we never got your mailed in change of address, so you're in trouble...???
