I had lots of problems when I moved.
I sent AR-11. I notified the 1-800 number that I moved. I followed up 6 months later to make sure that they have my correct address. I followed up a another 3 months after that. Along the way, my lawyer moved. He sent all the info to the USCIS about his noew address. Then my company changed lawyers all together, and they filed a new G-28 (?). Then my case got transferred to the local office for an interview. The local office did NOT have my new address. They were sending everything to my old address. They were sending a copy to the lawyer, but of course they were sending it to the old lawyer. And since he had moved, they were sending it to my old lawyer's OLD address. Luckily, the post office forwarded the letters to my old lawyer's new address. He was kind enough to promptly notify me and my new lawyer, but many lawyers are not this coopertive once you leave them. Nothing ever got forwarded to me from my old address, even though I had renewed my forwarding info every 6 months, in anticipation that this would happen.
I later dicsoverd that they have my address in several systems. Only 1 had been updated, and the systems that trigger some of the notices had the the wrong address.
In the end, I got my address corrected at the interview, when I pointed out that thay have my incorrect address. It could have ended much more badly. I was lucky, since I had an interview, and I was able to correct it IN PERSON. I know that they verify for your address, when you go for the stamping too, but if I had not had an interview, who knows if they would have corrected it the correct system.
Bottom line, if it wasn't for my old lawyer, I would have never been notified. If you have a choice, try to wait until you get your card before you move. Just my 2 cents.
