 In 1929, Stevens returned to the United States and began to study law, taking classes at the American University and Columbia University in international law and foreign policy. In 1930, she returned to Havana in February for the first meeting of the CIM women which included Flora de Oliveira Lima (Brazil), Aída Parada (Chile), Lydia Fernández (Costa Rica), Elena Mederos de González (Cuba), Gloria Moya de Jiménez (Dominican Republic), Irene de Peyré (Guatemala), Margarita Robles de Mendoza (Mexico), Juanita Molina de Fromen (Nicaragua), Clara González (Panama), Teresa Obregoso de Prevost (Peru). From Cuba, she went to the The Hague for the first World Conference on the Codification of International Law held on 13 March. Presenting her data on what had been accomplished in the Americas, Stevens asked that the international community enact laws to protect women's citizenship. She returned to the United States and her studies. Though she didn't graduate, in 1931 she became the first woman member of American Institute of International Law. That same year, she, Belmont and Paul attended the League of Nations meeting in September to present their nationality findings.
