Born in New York, she spent the first ten years of her childhood in the Dominican Republic, until her father's involvement in a political rebellion forced her family to flee the country. Many of Alvarez's works are influenced by her experiences as a Dominican in the United States, and focus heavily on issues of assimilation and identity. Her cultural upbringing as both a Dominican and an American is evident in the combination of personal and political tone in her writing. She is known for works that examine cultural expectations of women both in the Dominican Republic and the United States, and for rigorous investigations of cultural stereotypes. In recent years, Alvarez has expanded her subject matter with works such as '"In the Name of Salomé" (2000)', a novel with Cuban rather than solely Dominican characters and fictionalized versions of historical figures.
