Texas is under no obligation to educate illegals. Stop giving out free stuff. If a child is not a legal resident, then don't let them be enrolled.

A group of Texas Hispanic parents fought for their children’s right to attend public school. The Supreme Court decision Plyler v. Doe ruled in their favor. “The right to a basic education is a fundamental part of democracy," says historian Sonia Hernandez.
This week marks the 40th anniversary of a court case that affected thousands of schoolchildren. Yet it's one that most Americans likely don't know about.
In the 1970s, a group of Texas parents who lacked legal immigration status risked deportation to fight for their children’s right to attend public school. The case went all the way to the Supreme Court, which on June 15, 1982, ruled in favor of the parents and their children.
Plyler v. Doe ensured that children living in the U.S. without legal immigration documentation could access a basic education and lead more productive lives. It also paved the way for young immigrants to become active in efforts to demand legal pathways for children who have spent most of their lives in the U.S., such as the DREAM Act and the Deferred Action for Childhood Arrivals program, known as DACA.
