The first woman to lead a national organization fighting for immigrant rights was Angelina G. Castillo, who became the president of the American Coalition for Immigrant Rights. Castillo championed the cause of immigrants, advocating for policies to protect their rights and improve their living conditions in the U.S. Her leadership helped bring visibility to the challenges faced by immigrant communities and promoted legislative advocacy aimed at securing equal rights. Castillo’s work has inspired many activists in the ongoing fight for immigrant justice.
