If you were Japanese...even if you were a US citizen, you were sent to a camp. From Wikipedia: The internment of Japanese Americans in the United States was the forced relocation and incarceration during World War II of between 110,000 and 120,000 people of Japanese ancestry who lived on the Pacific coast in camps in the interior of the country. Sixty-two percent of the internees were United States citizens.The U.S. government ordered the removal of Japanese Americans in 1942, shortly after Imperial Japan's attack on Pearl Harbor.
