ICE uses 'criminal alien' and phrases like 'criminal illegal alien' or 'worst of the worst' as operational/descriptive labels for noncitizens ICE prioritizes for arrest because of criminal convictions or assessed public‑safety threat; they are not single, formal statutory classifications in immigration law (immigration law instead defines specific categories such as 'aggravated felony' or removability grounds).
wow.dhs.gov (Worst of the Worst) is a DHS public webpage that aggregates ICE/DHS press‑release lists of named ‘‘worst’’ criminal noncitizens; entries typically summarize alleged convictions/offenses and locations and link to agency press releases, but the site does not uniformly publish full court records, conviction dates, or up‑to‑date custody/removal status for every individual.
The '70%' figure is presented by DHS/ICE in its releases (an internal agency statistic) rather than an independent academic or judicial source; DHS/ICE releases citing that percentage do not always specify the precise time window in the single‑release text, so the figure should be treated as an agency statistic tied to ICE operational reporting (contact ICE/DHS for methodology/timeframe).
Typical next steps after ICE arrests a noncitizen with a criminal conviction can include a combination of actions: criminal prosecution (if new crimes), transfer to immigration custody for administrative detention, initiation of removal (deportation) proceedings before an immigration judge, and (where applicable) coordination with U.S. Attorneys to prosecute immigration‑related crimes; which steps occur depends on the case and applicable enforcement priorities and statutes.
DHS press releases list convicted individuals but often do not state when the underlying convictions occurred; the release in question names convictions without always giving full conviction dates or direct court records on the page — independent verification requires checking state/federal court dockets or local clerk records cited in the release.
ICE Enforcement and Removal Operations (ERO) field offices, ICE special agents, and CAP/Fugitive Operations commonly conduct these arrests; press releases sometimes identify which ICE field office or ERO unit made the arrest and may note coordination with local police or U.S. Marshals, but the DHS release at hand does not specify every office — detailed arresting units/partner agencies are usually listed in the corresponding ICE news release or local law‑enforcement statements.
ICE identifies and prioritizes individuals using enforcement priorities, programs (e.g., Criminal Alien Program, fugitive operations), and local/state criminal‑record checks; criteria are operational (criminal conviction/charges, national‑security/public‑safety risk, recent unlawful entry) described in ICE/DHS enforcement‑priority guidance rather than a single statutory 'worst of the worst' legal category—DHS published the WOW site to highlight those ICE‑prioritized arrests.
