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.

Rosenberg began her time at Reuters in Guatemala, filing dispatches on extrajudicial prison killings and the legacy of that country’s repressive human rights history. She later became a senior correspondent in Mexico City and reported from 10 countries across the region, including Haiti, Honduras and Venezuela, following everything from natural disasters to political coups. Her 18-month investigation with colleagues into corrupt deals worth billions of dollars at Mexico’s state-run oil company triggered probes by Mexican authorities.

She completed a Knight Bagehot Fellowship in business journalism and has a master’s degree from Columbia’s School of International and Public Affairs. She is originally from New Mexico and is now based in Brooklyn, New York.
