In 1943, the War Relocation Authority (WRA) issued all adult internees a questionnaire assessing their level of Americanization. It was entitled "Application for Leave Clearance". Questions asked about what language they spoke most frequently, their religion, and recreational activities. Participating in judo and kendo were "Japanese" activities, while playing baseball or being Christian were considered "American". Two questions asked prisoners if they were willing to fight in the US Armed Forces and if they would swear allegiance to the United States and renounce loyalty to the Emperor of Japan. Many Japanese-born Issei, who were barred from attaining American citizenship, resented the second question, feeling that an affirmative answer would leave them effectively stateless. Some Issei volunteered to join the army, even though there was no enlistment procedure for non-citizens. Others objected on other political grounds. In Topaz, nearly a fifth of male residents answered "no" to the question about allegiance. Inmates expressed their anger through a few scattered assaults against other inmates who they perceived as too close to the administration. Chiura Obata was among those attacked, resulting in his immediate release for fear of further assaults. A reworded version of the questionnaire for Issei did not require them to renounce their loyalty to the emperor of Japan. In response to the questionnaires, some Nisei formed the Resident Council for Japanese American Civil Rights, which encouraged other prisoners to register for the draft if their civil rights were restored.
