Mara first worked with immigrants and refugees through resettlement and hospitality at Casa de los Amigos in Mexico City. After returning to the United States in 2014 she began her work in immigration legal services with the National Immigrant Justice Center in Goshen, Indiana. While at NIJC, she became partially accredited and much of her work focused on asylum seekers, unaccompanied minors and survivors of domestic violence. After taking a few years off to attend seminary, Mara rejoined the world of immigration law in 2020 with Project Hope-Proyecto Esperanza in Archbold, Ohio, where she was reaccredited and has focused her work on representing clients seeking humanitarian forms of immigration relief. In 2021, Mara received full accreditation from the Department of Justice.
