The History of Denaturalization in the United States
Denaturalization—the legal process of revoking U.S. citizenship from naturalized individuals—has evolved significantly over the last century. Initially used after the 1906 Naturalization Act to correct fraud, it quickly became a tool to target those deemed “un-American” based on race, ideology, or conduct. During World War II, the practice expanded under the 1940 Nationality Act to include both naturalized and native-born citizens. However, in 1967, Afroyim v. Rusk limited the government’s denaturalization powers by affirming citizenship as a constitutional right. Today, denaturalization is rare and generally limited to cases involving fraud or human rights violations. Under recent administrations—particularly Trump’s—it has reemerged as a federal enforcement priority, raising due process concerns.
