Qingming...Thank you for your info. It helped.
After seeing your posting, I called INS to update my address. Earlier I sent g-734v form to update my address but I\'m not sure whether it was done. I am waiting for cards. IIO was very courteous but was in a hurry. She asked me A# and asked me the address and updated immediately. That was it. It\'s done. Scary thing was, there is no verification of my name, my old address etc. She did not check the number I gave was the right one or not. I really appreciate their trust in the callee, but atleast some check should be there while changing crucial information. I just want to thank you for posting such valuable information.
