Arizona has the highest number of applicants for a program allowing some undocumented youth get temporary deportation relief and permission to work.
More than half of eligible Deferred Action for Childhood Arrivals youth have applied, which is about 23,000, according to a new study released Wednesday by a nonpartisan organization in Washington, Migration Policy Institute.
About 20,00 of those have been approved.
However, the state has denied driver's licenses for DACA recipients at the directive of Gov. Jan Brewer. A federal appeals court overturned her orders last month. Brewer is appealing the decision, and the policy will remain in the meantime.
The program has been in place since 2012.
