One senior official said the Dreamers would be given legal status so long as they were productive, law-abiding members of American society. The official said a path to citizenship was only a discussion point and would only be available to about 690,000 young immigrants who signed up for legal protections under an Obama-era program known as Deferred Action for Childhood Arrivals, or DACA. Legal status would not be extended to those who were eligible for the program but failed to register, the official said.
