CHAPTER 3 —ALIEN ENEMIES
§21. Restraint, regulation, and removal
Whenever there is a declared war between the United States and any foreign nation or government, or any invasion or predatory incursion is perpetrated, attempted, or threatened against the territory of the United States by any foreign nation or government, and the President makes public proclamation of the event, all natives, citizens, denizens, or subjects of the hostile nation or government, being of the age of fourteen years and upward, who shall be within the United States and not actually naturalized, shall be liable to be apprehended, restrained, secured, and removed as alien enemies. The President is authorized in any such event, by his proclamation thereof, or other public act, to direct the conduct to be observed on the part of the United States, toward the aliens who become so liable; the manner and degree of the restraint to which they shall be subject and in what cases, and upon what security their residence shall be permitted, and to provide for the removal of those who, not being permitted to reside within the United States, refuse or neglect to depart therefrom; and to establish any other regulations which are found necessary in the premises and for the public safety.

Proc. No. 10903. Invocation of the Alien Enemies Act Regarding the Invasion of the United States by Tren de Aragua
Proc. No. 10903, Mar. 14, 2025, 90 F.R. 13033, provided:
Tren de Aragua (TdA) is a designated Foreign Terrorist Organization with thousands of members, many of whom have unlawfully infiltrated the United States and are conducting irregular warfare and undertaking hostile actions against the United States. TdA operates in conjunction with C[aacute]rtel de los Soles, the Nicolas Maduro regime-sponsored, narco-terrorism enterprise based in Venezuela, and commits brutal crimes, including murders, kidnappings, extortions, and human, drug, and weapons trafficking. TdA has engaged in and continues to engage in mass illegal migration to the United States to further its objectives of harming United States citizens, undermining public safety, and supporting the Maduro regime's goal of destabilizing democratic nations in the Americas, including the United States.
TdA is closely aligned with, and indeed has infiltrated, the Maduro regime, including its military and law enforcement apparatus. TdA grew significantly while Tareck El Aissami served as governor of Aragua between 2012 and 2017. In 2017, El Aissami was appointed as Vice President of Venezuela. Soon thereafter, the United States Department of the Treasury designated El Aissami as a Specially Designated Narcotics Trafficker under the Foreign Narcotics Kingpin Designation Act,
Like El Aissami, Nicolas Maduro, who claims to act as Venezuela's President and asserts control over the security forces and other authorities in Venezuela, also maintains close ties to regime-sponsored narco-terrorists. Maduro leads the regime-sponsored enterprise C[aacute]rtel de los Soles, which coordinates with and relies on TdA and other organizations to carry out its objective of using illegal narcotics as a weapon to "flood" the United States. In 2020, Maduro and other regime members were charged with narcoterrorism and other crimes in connection with this plot against America.
Over the years, Venezuelan national and local authorities have ceded ever-greater control over their territories to transnational criminal organizations, including TdA. The result is a hybrid criminal state that is perpetrating an invasion of and predatory incursion into the United States, and which poses a substantial danger to the United States. Indeed, in December 2024, INTERPOL Washington confirmed: "Tren de Aragua has emerged as a significant threat to the United States as it infiltrates migration flows from Venezuela." Evidence irrefutably demonstrates that TdA has invaded the United States and continues to invade, attempt to invade, and threaten to invade the country; perpetrated irregular warfare within the country; and used drug trafficking as a weapon against our citizens.
Based upon a review of TdA's activities, and in consultation with the Attorney General and the Secretary of the Treasury, on February 20, 2025, acting pursuant to the authority in
As President of the United States and Commander in Chief, it is my solemn duty to protect the American people from the devastating effects of this invasion. NOW, THEREFORE, I, DONALD J. TRUMP, President of the United States of America, by the authority vested in me by the Constitution and the laws of the United States of America, including the Alien Enemies [sic] Act,
Pursuant to the authority vested in me by the Constitution and the laws of the United States of America, including the Alien Enemies Act,
(a) No Alien Enemy described in section 1 of this proclamation shall enter, attempt to enter, or be found within any territory subject to the jurisdiction of the United States. Any such Alien Enemy who enters, attempts to enter, or is found within such territory shall be immediately apprehended and detained until removed from the United States. All such Alien Enemies, wherever found within any territory subject to the jurisdiction of the United States, are subject to summary apprehension.
(b) Alien Enemies apprehended pursuant to this proclamation shall be subject to detention until removed from the United States in such place of detention as may be directed by the officers responsible for the execution of these regulations.
(c) Alien Enemies shall be subject to removal to any such location as may be directed by the officers responsible for the execution of these regulations consistent with applicable law.
(d) All property in the possession of, or traceable to, an Alien Enemy, which is used, intended to be used, or is commonly used to perpetrate the hostile activity and irregular warfare of TdA, along with evidence of such hostile activity and irregular warfare, shall be subject to seizure and forfeiture.
The Attorney General is further granted authority, pursuant to the Alien Enemies Act and
This proclamation and the directives and regulations prescribed herein shall extend and apply to all land and water, continental or insular, in any way within the jurisdiction of the United States.
IN WITNESS WHEREOF, I have hereunto set my hand this fourteenth day of March, in the year of our Lord two thousand twenty-five, and of the Independence of the United States of America the two hundred and forty-ninth.
Donald J. Trump.
