My wife's I-485 was approved on June 29, 2005 and received the plastic card dated June 29, 2004. Unfortunately we received a letter from CIS today requiring to replace the card due to error in "residence since" date. I made several calls to the custmer services to declare there is no error at all and at least 2 IOs said that they never heard of one-year-date -back policy. My attorney said that they were wrong.But I could not find anything in writing to proof CIS's one year date back policy. Please give me some inputs!!!
