It's been nearly five years since president Barack Obama signed the executive order known as DACA, Deferred Action for Childhood Arrivals. It gave "protected status" to immigrants who had arrived in the U.S. before they turned 16.
DACA allowed them to remain in the U.S., work, obtain a driver's license and study. More than 750,000 registered and were vetted. DACA, however, did not offer them a pathway to citizenship. It just meant they would not be deported.
