In United States immigration enforcement, "catch and release" refers to a practice of releasing a migrant to the community while he or she awaits hearings in immigration court, as an alternative to holding them in immigration detention.[1][2] The migrants whom U.S. immigration enforcement agencies have allowed to remain in the community pending immigrant hearings have been those deemed low risk,[3] such as children, families, and those seeking asylum.[4]
There is no "hard-and-fast definition" of the phrase,[2] which can be used as a pejorative.[5][6] Rather, the phrase refers to a "collection of policies, court precedents, executive actions and federal statutes spanning more than 20 years, cobbled together throughout Democratic and Republican administrations."[2] The Trump administration has used the phrase as a catch-all term for laws or policies preventing the holding of apprehended migrants in immigration detention.[4]
