DACA is an Obama-era program that provides temporary relief from deportation and work permits to undocumented immigrants who came to the US as children. It started in 2012 and allows those who meet certain guidelines, such as arriving before age 16 and having no felony convictions, to apply for renewable two-year periods of deferred action. While DACA does not provide a path to citizenship, it allows qualifying individuals to work legally and protects them from deportation. However, the program's constitutionality has been questioned since its inception by executive order rather than legislation.
