Presents data on criminal and civil immigration violations handled by the federal justice system over the last decade. The report examines the various ways immigration violator cases are processed based on the type of offense, the suspect's prior record, and the district in which the suspect is apprehended. Tables describe the demographic characteristics of criminal immigration offenders, adjudication and sentencing outcomes, and the number of criminal immigration offenders returning to federal prison within 3 years of release from previous federal imprisonment. Data in the report come from the Federal Justice Statistics Program (FJSP) and from documentation published by the Department of Homeland Security (DHS) and the Executive Office for Immigration Review (EOIR).

For 2002 and 2003 data, age was computed incorrectly as age at commitment instead of age at fiscal yearend. After 2004, age was computed correctly as age at fiscal yearend. To ensure consistency for all years, table 13 and associated text in the report were corrected to display all years as age at fiscal yearend.
