回复：Please help for changing address!!!!!!!!!

Call USCIS in the morning.
1-800-375-5283
press [1] for english
press [2] for filed application
press [1] for change address

You need the I-485 recipt WAC number and the A# number.
If your wife/hu*****and filed I-485 with you, you need her/his WAC number and A# number as well, and you also need her/him to talk to the USCIS representative on the phone (simply speak out her/his name).

I know above detail because I just called USCIS to change address two days ago, I had to get hold of my wife and luckly my cell phone has "Speaker" phone mode, which I could switch on and let the representative hear my wife's voice.
