This report examines the policies and practices of Illinois public colleges and universities in the admission of undocumented residents as well as the nature of the participation of rapidly increasing race/ethnic groups in higher education and strategies to increase their participation. The 2000 U.S. Census showed that the Hispanic population of Illinois increased by 69% in the past decade, and the Asian population increased by 53%. In 2000, 1.5 million Illinois residents were foreign-born. An estimated 500,000 Illinois residents are "undocumented," in that they are immigrants without legal authorization to stay in the United States. Records from public institutions of higher education show that Hispanics are underrepresented in higher education, but Asian students are not. Public institutions vary in the way in which they treat undocumented applicants for admission. Many institutions report that they do not receive applications from undocumented persons. Some will not process such an application without proper legal documents, and others consider the applicant to be a foreign student. The University of Illinois and Northeastern Illinois admit undocumented students and permit them to pay instate tuition if they meet certain qualifying conditions. Some colleges do not even ask about U.S. citizenship or immigration status. The report proposed various strategies to improve the participation of rapidly increasing race/ethnic groups that are underrepresented in higher education, including requiring a vigorous high school curriculum, improving teacher education and teacher quality, ensuring that college is affordable for all, placing higher priority on those who seek English proficiency, and valuing diversity in Illinois higher education.
