Border security is critically important to the national security of the United States.  Aliens who illegally enter the United States without inspection or admission present a significant threat to national security and public safety.  Such aliens have not been identified or inspected by Federal immigration officers to determine their admissibility to the United States.  

The recent surge of illegal immigration at the southern border with Mexico has placed a significant strain on Federal resources and overwhelmed agencies charged with border security and immigration enforcement, as well as the local communities into which many of the aliens are placed.

Transnational criminal organizations operate sophisticated drug- and human-trafficking networks and smuggling operations on both sides of the southern border, contributing to a significant increase in violent crime and United States deaths from dangerous drugs.  Among those who illegally enter are those who seek to harm Americans through acts of terror or criminal conduct.  

Continued illegal immigration presents a clear and present danger to the interests of the United States.

Federal immigration law both imposes the responsibility and provides the means for the Federal Government, in cooperation with border States, to secure the Nation's southern border.  Although Federal immigration law provides a robust framework for Federal-State partnership in enforcing our immigration laws  and the Congress has authorized and provided appropriations to secure our borders    the Federal Government has failed to discharge this basic sovereign responsibility.  

The purpose of this order is to direct executive departments and agencies (agencies) to deploy all lawful means to secure the Nation's southern border, to prevent further illegal immigration into the United States, and to repatriate illegal aliens swiftly, consistently, and humanely.
