U.S. Citizenship and Immigration Services (USCIS) is transforming its operations by creating a new electronic environment known as the USCIS Electronic Immigration System (USCIS ELIS), which allows individuals requesting a USCIS benefit to register online and submit certain benefit requests through the online system. This system will improve customer service; increase efficiency for processing benefits; better identify potential national security concerns, criminality, and fraud; and create improved access controls and better auditing capabilities. This Privacy Impact Assessment (PIA) is being conducted because USCIS ELIS collects and uses personally identifiable information (PII). This new electronic environment is divided into three distinct processes: 1) Temporary Account and Draft Benefit Requests; 2) Account and Case Management; and 3) Automated Background Functions. This PIA addresses the Account and Case Management process by describing how USCIS ELIS uses information provided on initial and subsequent benefit requests and subsequent collections to create or update USCIS ELIS accounts; gather any missing information; manage workflow; assist USCIS in making a benefit determination; and provide a repository of data to assist with future benefit requests.
