回複：485改地址的電話煩惱，白兔等高手看看

You are too serious. When I received the conform letter for address change from USCIS, my name and my wife name were all wrong in the letter. they are making mistake every day and they are not serious. I do not think there will be a problem with such mistake and so I never contacted them. Do not look at the GC so seriously. It is just GC. Relax and enjoy life, not the GC.
