USIS
USIS is a four-character combination (4CC) that may refer to:
- United States Information Service, the overseas name for the (now-defunct) United States Information Agency
- United States Immigration Service, a name sometimes used in the past, possibly both formally and informally at different times, to refer to at least one of the many U.S. federal agencies of the executive branch that have implemented U.S. immigration law at different times. (Today the principal such agency is ICE [Immigration and Customs Enforcement].)
- Student automation system of Yıldız Technical University
- USIS or US Investigations Services
USIS is the privatized arm of the Office of Personnel Management's Office of Federal Investigations, which was privatized in 1996 and became US Investigations Services, or USIS. The company began as an employee-owned company, but has since been purchased by private investors and is now owned by The Carlyle Group and Welsh, Carson, Anderson & Stowe. Since OPM’s privatization of its federal investigators, approximately 2000 investigators from the Defense Security Service have been transferred to OPM, and OPM has since reconstituted its federal investigations program in the Center for Federal Investigative Services, located within OPM. OPM is responsible for the bulk of security clearance investigations, but it contracts out most of this work. USIS was initially awarded a sole-source no-bid contract for conducting investigations, but since the initial contract other companies have been awarded parts of investigations contract, included Kroll Government Services, SA-TECH, CACI, Inc., and Omniplex.
