The Oklahoma State Board of Education voted Tuesday to approve a proposal requiring parents to report their immigration or citizenship status when enrolling their children in school.

Parents enrolling children in Oklahoma public schools will be required to provide proof of their child’s U.S. citizenship or legal immigration status under a proposal rule approved by the State Board of Education.

State Superintendent Ryan Walters says a proposed administrative rule concerning immigration status could be used on parents as well as students.

Oklahoma may require parents to report their immigration status when enrolling children in schools. “We're not going to allow sanctuary schools here in Oklahoma,” Superintendent of Public Instruction Ryan Walters told CNN’s Brianna Keilar on Tuesday afternoon.

Families enrolling children in Oklahoma public schools will have to provide proof of their U.S. citizenship under new rules approved Tuesday by the state’s education board.

The rule would not block undocumented students from enrolling, but it would supply the Trump administration with information to aid immigration enforcement.
