During 2014 there was a sharp increase in Unaccompanied Alien Children (UAC) that lead the CBP and ICE seeking better ways to communicate across agencies so a humanitarian way to deal with the situation would be available for all.
Also in 2014 CBP raised their readiness to "Level IV" indicating that they have went to the highest level of contingency planning and awareness within the DHS. CBP Facilities were not designed to handle such large numbers of UAC even for a short period of 72 hours.
On February 23, 2016 CBP released it's statement that it has augmented it's processing capability by instituting virtual processing and assigning several stations to assist in the care and custody of UAC while the children were awaiting transfer to the custody of the U.S. Department of Health and Human Services or the Office of Refugee Resettlement.
On February 23, 2016 ICE released a similar albeit different statement that set out the steps to address the issue as such:
"Secretary Johnson has made clear that recent border entrants and those apprehended attempting to cross the border unlawfully are top enforcement priorities as indicated in the November 2014 enforcement priorities memorandum. Consistent with our laws and values, recent border crossers, including those apprehended as unaccompanied children, who are unable to establish they are eligible for relief and exhausted appeals have been, and will continue to be, ICE removal priorities.
Secretary Johnson, Director Saldaña, and I have also personally met with high level officials from Mexico, Honduras, El Salvador, and Guatemala to secure their cooperation in stemming the illegal flow of their citizens into the United States. These partnerships have also resulted in enhanced cooperation between ICE and law enforcement partners in Central America and Mexico to combat and prosecute human trafficking and smuggling organization networks illegally smuggling hundreds of individuals – including children and families – throughout Central America and Mexico into the United States."
