Can students come to live with U.S. citizen relatives while attending public school?
Foreign students may come to the U.S. to live with U.S. citizen relatives while attending public school. The child is limited to twelve months of study in secondary school (high school). The child may not study in elementary school. It should be noted however, that the student's status as a resident of the school district and the fact that the U.S. citizen has paid local property/school taxes is irrelevant and does not fulfill the cost reimbursement requirement of the Immigration and Nationality Act (INA) 214 (m). Therefore,the full tuition costs must be paid to the school or school district.
