Undocumented youth in the United States are young people living in the United States without U.S. citizenship or other legal immigration status. An estimated 1.1 million undocumented minors resided in the U.S. as of 2010, making up 16% of the undocumented population of 11 million. Undocumented students face unique legal uncertainties and limitations within the United States educational system. They are sometimes called the 1.5 generation, as they have spent a majority of their lives in the United States.

Citizenship of the United States is a legal status that entails Americans with specific rights, duties, protections, and benefits in the United States. It serves as a foundation of fundamental rights derived from and protected by the Constitution and laws of the United States, such as freedom of expression, due process, the rights to vote, live and work in the United States, and to receive federal assistance.
