A new Trump decree will eliminate DACA (Deferred Action for Childhood Arrivals). DACA was established by the Obama administration to provide work authorization and deferral of deportation to young people who came to the US while under the age of 16, and who have graduated from high school, attended college, are currently attending school or have served honorably in the U.S. military.
This new edict abolishes the DACA program, although it allows current beneficiaries of DACA to continue working until their current two-year work authorization expires. Thus, it abolishes any new applications for DACA as well as any extensions. From the wording of the edict, it appears that those unfortunates with pending applications will be denied. It also allows US ICE (Immigration and Customs Enforcement) to initiate removal proceedings against dreamers, although it allows ICE to exercise prosecutorial discretion to decide on a case-by-case basis not to deport individual dreamers who already have work authorization.
It also eliminates DAPA, which provided for deferred action for the parents of U.S. citizens and lawful permanent residents, but which never went into effect because of the injunction in the Texas v. US litigation.
