The Trump administration has announced a new crackdown on immigrants applying for green cards to live and work in the United States. Under the proposed new rules, applicants could be denied green cards if they have ever used public assistance, including food assistance or housing vouchers, or received discounted prescription drugs through Medicare Part D. The National Immigration Law Center slammed the proposed rule change, saying it would rig the nation’s immigration system so green cards would only go to the highest bidder. The group says, “This is a regulatory backdoor approach to separate more families.” The mayor of Los Angeles, Eric Garcetti, vowed to fight the rule change, saying, “Hundreds of thousands of our neighbors may be unable to see their doctors, keep a roof over their heads or afford a trip to the grocery store, if they wish to remain in the United States. That is simply wrong and un-American.”
