(a) Notwithstanding any other provision of this code, if a student is required, as a condition of obtaining or holding the appropriate United States student visa, to pay tuition to the school district or open-enrollment charter school that the student attends to cover the cost of the student’s education provided by the district or charter school, the district or charter school shall accept tuition for the student in an amount equal to the full unsubsidized per capita cost of providing the student’s education for the period of the student’s attendance at school in the district or at the charter school.
(b) The commissioner shall, for purposes of Subsection (a), develop guidelines for determining the amount of the full unsubsidized per capita cost of providing a student’s education. A school district or open-enrollment charter school may not accept tuition in an amount greater than the amount computed under the commissioner’s guidelines unless the commissioner approves a greater amount as a more accurate reflection of the cost of education to be provided by the district or charter school.

(c) Notwithstanding any other provision of this code, the attendance of a student for whom a school district or open-enrollment charter school accepts tuition under this section is not counted for purposes of allocating state funds to the district or charter school.
