Mica Rosenberg is an investigative reporter on ProPublica’s national desk focusing on immigration. Rosenberg previously worked at Reuters, where she and her colleagues published a 2022 investigation exposing migrant child labor in the United States; that series spurred government investigations, was a finalist for the Pulitzer Prize and won a George Polk Award, among other honors. Her other work explored rising death tolls and changing demographics at the U.S.-Mexico border, facilitated by increasingly lucrative international smuggling networks. In the early days of the pandemic, she revealed disparities in COVID-19 infections among immigrant communities and the government negligence that caused unnecessary deaths in immigration detention. She also worked on projects examining some of the longstanding inequities in the immigration court system and the unregulated world of labor brokers bringing temporary workers into the country. Before covering immigration, she reported on legal affairs and white-collar crime in New York.
