and assimilation efforts in the camps, taking data from observations of and interviews with camp residents. While some community analysts viewed the Japanese American inmates merely as research subjects, others opposed the incarceration and some of the WRA's policies in their reports, although very few made these criticisms public. Restricted by federal censors and WRA lawyers from publishing their full research from the camps, most of the (relatively few) reports produced by the CAS did not contradict the WRA's official stance that Japanese Americans remained, for the most part, happy behind the barbed wire. Morris Opler did, however, provide a prominent exception, writing two legal briefs challenging the exclusion for the Supreme Court cases of Gordon Hirabayashi and Fred Korematsu. Resettlement program Concerned that Japanese Americans would become more dependent on the government the longer they remained in camp, Director Dillon Myer led the WRA in efforts to push inmates to leave camp and reintegrate into outside communities. Even before the establishment of the "relocation centers," agricultural laborers had been issued temporary work furloughs by the WCCA, and the National Japanese American Student Relocation Council had been placing Nisei in outside colleges since the spring of 1942. The WRA had initiated its own "leave permit" system in July 1942, although few took the trouble to go through the bureaucratic and cumbersome application process until it was streamlined over the following months. (By the end of 1942, only 884 had volunteered for resettlement.) The need for a more easily navigable system, in addition to external pressure from pro-incarceration politicians and the general public to restrict who could exit the camps, led to a revision of the application process in 1943. Initially, applicants were required to find an outside sponsor, provide proof of employment or school enrollment, and pass an FBI background check. In the new system, inmates had only complete a registration form and pass a streamlined FBI check. (The "loyalty questionnaire," as the form came to be known after it was made mandatory for all adults regardless of their eligibility for resettlement, would later spark protests across all ten camps.) At this point, the WRA began to shift its focus from managing the camps to overseeing resettlement. Field offices were established in Chicago, Salt Lake City and other hubs that had attracted Japanese American resettlers. Administrators worked with housing, employment and education sponsors in addition to social service agencies to
