In Pennsylvania a new law has been passed requiring construction companies to run immigration checks on all of their employees through a federal database, E-Verify. Pennsylvania follows the trend of over 20 states to implement similar laws. Many Union leaders in support of the new legislation claim that the legislation is pro-labor and will mean more jobs for union members. However, critics of the new legislation worry that it is just promoting additional anti-immigrant sentiment in Pennsylvania.
