change address

I changed address after I-140 was approved. I mailed AR-11 form to the following address about 9 months ago.
U.S. DEPARTMENT OF HOMELAND SECURITY
Bureau of Citizenship and Immigration Services
Change of Address
P.O. Box 7134
London, KY 40742-7134

How do I know my address has been updated? Is there any way to find out?

Thanks a lot!!!
