In January and March 2017, the President issued a series of executive orders related to border security and immigration. The orders direct federal agencies to take a broad range of actions with potential resource implications. For example, Executive Order 13767 instructs DHS to construct a wall or other physical barriers along the U.S. southern border and to hire an additional 5,000 U.S. Border Patrol agents. Executive Order 13768 instructs federal agencies, including DHS and DOJ, to ensure that U.S immigration law is enforced against all removable individuals and directs ICE to hire an additional 10,000 immigration officers. Executive Order 13780 directs agencies to develop a uniform baseline for screening and vetting standards and procedures; and established nationality-based entry restrictions with respect to visa travelers for a 90-day period, and refugees for 120 days. For the last several years, Central American migrant families have arrived at the U.S.-Mexico border in relatively large numbers, many seeking asylum. Federal immigration laws set forth procedures governing the exclusion and removal of non-U.S. nationals (aliens) who do not meet specified criteria regarding their entry or presence within the United States. Typically, aliens within the United States may not be removed without due process
