Battered immigrant women relay extremely sensitive and private information to the U.S. Citizenship and Immigration Services (CIS, formerly INS)3 when seeking immigration relief. A batterer in possession of any of this information might use it to locate the battered immigrant spouse and her children and harm them. If he becomes aware that she is seeking immigration status independently of him or planning on leaving him, he might try to seek revenge and might contact the immigration authorities in an attempt to undermine her case or have her deported. For these reasons, confidentiality rules can serve as a potentially lifesaving protection for the victim and her children. A manual of confidentiality and breaches of confidentiality.
