Immigration Enforcement Actions

The Department of Homeland Security (DHS) engages in immigration enforcement actions to prevent unlawful entry into the United States and to apprehend and repatriate aliens who have violated or failed to comply with U.S. immigration laws. Primary responsibility for the enforcement of immigration law within DHS rests with U.S. Customs and Border Protection (CBP), U.S. Immigration and Customs Enforcement (ICE), and U.S. Citizenship and Immigration Services (USCIS). CBP enforces immigration laws at and between the ports of entry, ICE is responsible for interior enforcement and for detention and removal operations, and USCIS adjudicates applications and petitions for immigration and naturalization benefits.

Reconsideration of the June 15, 2012 Memo Entitled "Exercising Prosecutorial Discretion with Respect to Individuals Who Came to the United States as Children"

On June 15, 2012, Secretary of Homeland Security Janet Napolitano established the policy known as Deferred Action for Childhood Arrivals (DACA) through a memorandum entitled “Exercising Prosecutorial Discretion with Respect to Individuals Who Came to the United States as Children.” Ever since, the policy has been subject to substantial controversy. In recent years, Acting Secretary of Homeland Security Elaine Duke and Secretary of Homeland Security Kirstjen Nielsen concluded that the DACA policy should be fully rescinded and issued additional memoranda in 2017 and 2018, respectively, to effect that decision.

Los Protocolos de Protección a Migrantes

Los Protocolos de Protección a Migrantes [Migrant Protection Protocols (MPP)] constituyen una acción gubernamental de los Estados Unidos [U.S. Government (USG)] mediante la cual los ciudadanos y nacionales de países aparte de México, que llegan a los Estados Unidos por tierra desde México -- sea o no sea a través de un puerto de entrada -- podrían ser devueltos a México de conformidad con la Sección 235(b)(2)(C) de la Ley de Inmigración y Nacionalidad [Immigration and Nationality Act (INA)] mientras sus procedimientos de remoción se encuentren pendientes en los Estados Unidos bajo la Sección 240 de la INA.

Metrics and Measures

The Migrant Protection Protocols (MPP) are a U.S. Government (USG) action whereby citizens and nationals of countries other than Mexico arriving in the United States by land from Mexico -- whether or not at a point of entry -- may be returned to Mexico pursuant to Section 235(b)(2)(C) of the Immigration and Nationality Act (INA) while their U.S. removal proceedings are pending under Section 240 of the INA. MPP is a core component of the USG’s efforts to address the migration crisis along the U.S.-Mexico border.
