This week, the Supreme Court will hear oral arguments in the legal battle over Deferred Action for Childhood Arrivals, the 2012 policy that has temporarily protected from deportation many undocumented individuals who were brought to the United States as children. As a physician, I’m deeply concerned about the impact this decision will have on the health of the nation. Since the administration announced rescission of the program in 2017, the national discussion has focused, appropriately, on the impact that terminating DACA would have on the hundreds of thousands of young adults who rely on it to live, work and study in the United States.
