Marielena is an immigrant from Medellin, Colombia. Growing up in Rhode Island as the youngest of ten kids, she became an interpreter for her parents at schools, hospitals, and government agencies where she learned about the structural barriers and inequities facing poor people in this country, especially people of color and immigrants. For 20 years, she served as executive director of the National Immigration Law Center (NILC), the nation’s leading organization dedicated to defending and advancing the rights of low-income immigrants in the United States. Under her leadership, NILC has been at the legal forefront of the fight to stop President Trump’s attempt to rescind DACA, successfully representing DACA recipients and Make the Road New York in a U.S. Supreme Court case in which the Court found that the Trump administration’s rescission was “arbitrary and capricious.”
