The Renunciation Act of 1944
During World War II, 5,589 American citizens of Japanese descent renounced their U.S. citizenship. The renunciations took place between December 1944 and July 1945, mostly in Tule Lake concentration camp, California. The vast majority of renunciations had little to do with "disloyalty" to the U.S., but instead were the result of a series of complex conditions and events that were beyond the control of those involved. After a legal battle, most renunciants had their U.S. citizenship restored in the 1960s.
