Immigrants line up after spending the night outside a California Department of Motor Vehicles office to register for drivers licenses in Stanton, Calif., on Jan. 2, 2015. Hundreds of people packed into state offices and waited on hours-long lines Friday as California began issuing driver’s licenses to the nation’s largest population of immigrants in the country illegally. Braving near-freezing temperatures, immigrants donning scarves and gloves and poring over driver’s handbooks arrived at the newly-created Department of Motor Vehicles office in Stanton as early as 2 a.m. hoping to be among the first to obtain the long-sought driving permits.
