Public concerns regarding illegal immigration are currently polarizing the United States. Regardless of one's position, the children of illegal (also referred to as undocumented) immigrants are in a particularly vulnerable situation. While undocumented children are allowed free public primary and secondary education, their path to skills attainment and economic improvement may end at high school. Many state legislatures have yet to codify or coordinate policies to manage access for this growing population of students, a population that by 2015 will make up as much as 30 percent of all students. In fact, much policy confusion and inconsistency exists at both the state and federal level, particularly in regards to post-secondary education. The purpose of this paper is to provide an overview of the issues related to undocumented students and their access to public high education. Exploring state and federal regulations will illuminate how this issue may affect higher education administrators and the institutions at which they work. In conclusion, the authors provide recommendations on how higher education administrators may seek to mitigate the consequences of access for undocumented students.
