illegal alien

"Illegal alien" is a legal and political term used to describe a foreign national who has entered or resides in a country without government authorization. The noun "alien" derives from the Latin alienus, meaning "stranger" or "foreign," and has been a standard part of U.S. legal terminology since the late 18th century. The specific compound phrase became common in the mid-20th century to distinguish unauthorized entrants from those with legal status in statutory contexts.

Usage of the term is highly contested. Proponents argue it is the precise legal terminology found in federal statutes and accurately describes both the status (alien) and the nature of the residency (illegal/unauthorized). Critics, including many human rights organizations and journalistic style guides like the AP, reject the term as dehumanizing, arguing that actions can be illegal but people cannot. Opponents also note that being in a country without authorization is often a civil rather than criminal violation, making the adjective "illegal" misleading and stigmatizing.

Examples:

"The court reviewed the statute to determine if the defendant met the criteria of an illegal alien under federal law."

"Critics of the bill argued that using the term illegal alien in the legislation would alienate immigrant communities."
