回复：我的485有一年半没有Update, 其间曾打过两次电话

It's quite normal. at least it happened to me and my friends. If you havn't got any confirmation letter, it is very possibly that they havn't changed your address at all.

I updated my address a month ago, and today I called them again, they still have my old address in file. You just don't understand how these people work.
