Catch and release is the unofficial name for a protocol historically followed by immigration enforcement agencies in the United States (specifically, by U.S. Immigration and Customs Enforcement and U.S. Customs and Border Protection) where people caught for being in unlawful immigration status are released while they wait for a hearing with an immigration judge. The policy officially ended in 2006 under President George W. Bush and United States Department of Homeland Security Secretary Michael Chertoff, where it was replaced by a catch and return or catch and detain policy. However, some critics of immigration enforcement in subsequent years, particularly under the presidency of Barack Obama, have dubbed various policies and practices under the administration as catch-and-release policies
