Where any child of school age in any school district resides one and one-half miles or more by the nearest traveled road from the nearest public elementary school or three miles or more from the nearest high school in the district, such child unless proper free transportation is furnished to a suitable school in this Commonwealth may on request of his parents or legal guardian be assigned by the board of school directors to a more convenient school in another state: Provided, That the consent of the proper school officials in charge of such school in another state to such an arrangement is permitted by the laws of such state and is agreed to by such officials. The tuition of any such pupil attending a school in another state may be paid by the board of school directors of the district in which he is a resident, as in the case of a pupil attending a public school in this Commonwealth in a district in which he is not a resident.

The board of school directors in any school district situate adjacent to another state may admit to the public schools in such district pupils resident in such other state and may receive tuition for such pupils, as in the case of pupils admitted from other districts in this Commonwealth.
