More than 427,000 undocumented students are enrolled in U.S. higher education institutions. That's an impressive number, considering the many hurdles they must overcome on the road to college and a degree, including restrictions on their ability to enroll in higher education institutions; limits on access to in-state tuition, state financial aid, professional and commercial licenses, driver's licenses, state health care, and food and housing assistance; and difficulties obtaining work authorization and employment -- not to mention the threat of deportation they are under. Providing equitable higher education access for undocumented students means making college accessible and affordable for them. But it also means acknowledging the unique challenges they face because of their immigration status and ensuring that they get the additional supports they need. Researchers from The Education Trust analyzed 9 criteria in the 15 states with the largest shares of undocumented college students -- Arizona, California, Colorado, Florida, Illinois, Georgia, Maryland, Massachusetts, Nevada, New Jersey, New York, North Carolina, Texas, Virginia, and Washington -- to determine whether state policies are helping or hurting undocumented students' ability to attend college and how access and success for this underserved student population could be improved.
