USCIS guide for LPRs says:

" ... Give Your New Address to DHS
Every time you move, you need to tell DHS your new
address. You must file Form AR-11, Alien’s Change of
Address Card. There is no fee to file this form. You must
file this form within 10 days of your move.
Send Form AR-11 to:
Department of Homeland Security
U.S. Citizenship and Immigration Services
Change of Address
P.O. Box 7134
London, KY 40742-7134
For more information, call the USCIS at 1-800-375-5283 ... "

Does this mean that *every* LPR must report to the CIS every time they move?! With millions of LPRs moving every day how is this possible for the CIS to process and update their databases? Do you as an LPR really report every time you move?

That's what the law says. If you don't like it, why not naturalize?
