In 1982, the Supreme Court ruled in Plyler v. Doe that all children, regardless of immigration status, have the right to attend public school. This decision was based on the Equal Protection Clause of the Fourteenth Amendment, which prohibits states from denying any person "within its jurisdiction the equal protection of the laws." The Court held that education was essential to the success of all children, regardless of their immigration status, and that denying undocumented children access to education would harm not only the children themselves, but also society as a whole.
Since the Plyler decision, undocumented children have been able to attend public school in the United States without fear of being deported. However, there have been a number of attempts to challenge this ruling, and some states have passed laws that make it more difficult for undocumented children to enroll in school.
Despite these challenges, the Plyler decision remains the law of the land, and undocumented children continue to have the right to attend public school in the United States.
