8 U.S. Code § 1228: Expedited removal of aliens convicted of committing aggravated felonies--(c) Presumption of deportability: An alien convicted of an aggravated felony shall be conclusively presumed to be deportable from the United States
(5) Stipulated judicial order of removal: The United States Attorney, with the concurrence of the Commissioner, may, pursuant to Federal Rule of Criminal Procedure 11, enter into a plea agreement which calls for the alien, who is deportable under this chapter, to waive the right to notice and a hearing under this section, and stipulate to the entry of a judicial order of removal from the United States as a condition of the plea agreement or as a condition of probation or supervised release, or both. The United States district court, in both felony and misdemeanor cases, and a United States magistrate judge in misdemeanor cases, may accept such a stipulation and shall have jurisdiction to enter a judicial order of removal pursuant to the terms of such stipulation.
Among other things, federal law specifies categories of aliens who are ineligible to be admitted to the United States, 8 U. S. C. §1182; requires aliens to register with the Federal Government and to carry proof of status, §§1304(e), 1306(a); imposes sanctions on employers who hire unauthorized workers, §1324a; and specifies which aliens may be removed and the procedures for doing so, see §1227. Removal is a civil matter, and one of its principal features is the broad discretion exercised by immigration officials, who must decide whether to pursue removal at all. Immigration and Customs Enforcement (ICE), an agency within the Department of Homeland Security, is responsible for identifying, apprehending, and removing illegal aliens.
In the United States, the power to exclude or to expel aliens is vested in the political departments of the National Government, and is to be regulated by treaty or by act of Congress, and to be executed by the executive authority according to the regulations so established, except so far as the Judicial Department is authorized by treaty or by statute, or is required by the Constitution, to intervene. The power of Congress to expel, like the power to exclude, aliens, or any specified class of aliens, from the country, may be exercised entirely through executive officers; or Congress may call in the aid of the Judiciary to ascertain any contested facts on which an alien's right to remain in the country has been made by Congress to depend.
