This document offers statistical information regarding immigration court matters during the 2006 fiscal year (FY) of the Department of Justice. "An alien charged by the Department of Homeland Security (DHS) with a violation of immigration law is issued a charging document. The most common charging documents are the Notice to Appear (NTA) and the Notice of Referral to Immigration Judge. When the charging document is filed by DHS with the Immigration Court, jurisdiction over the case transfers from DHS to the Executive Office for Immigration Review (EOIR), which has oversight over the 53 Immigration Courts located throughout the United States. Once an alien has been ordered removed by EOIR, DHS carries out the removal; EOIR does not maintain statistics on alien removals from the United States. […] For the purposes of this Year Book, the term Immigration Court matters includes proceedings (deportation, exclusion, removal, credible fear, reasonable fear, claimed status, asylum only, rescission, continued detention review, NACARA [Nicaraguan Adjustment and Central American Relief Act], and withholding only), bond redeterminations, and motions. Receipts are defined as the total number of proceedings, bond redeterminations, and motions received by the Immigration Courts during the reporting period. Completions include Immigration Judge decisions on proceedings, bond redeterminations, and motions; other completions such as administrative closings and changes of venue."
