Section 1725 of the California Labor Code defines “alien” as “any person who is not a born or fully naturalized citizen of the United States.” Section 2015 sets forth the “preference for employment” for the extension of public works by the state and requires the extension of such preference “First, to citizens of this State. Second, to citizens of other States within the United States… Third, to aliens who are within the State.…” SB 432 law repeals both of these provisions.
