Classification 107: Denaturalization Proceedings (Obsolete)

This classification was established on June 28, 1944 for investigations of naturalized citizens of the United States who allegedly engaged in activities that indicated loyalty to another government. At the request of the Attorney General, the FBI Field Offices submitted names and information concerning potential candidates for denaturalization. Most of the cases opened in 1944-1946 and involved persons who allegedly were pro-Japanese. Some Japanese-Americans voluntarily renounced their citizenship with the intent of being repatriated to Japan. The classification was declared obsolete in 1952.
