Ohio Rev. Code § 3333.19
The chancellor of higher education may enter into agreements with the appropriate agency in a foreign country or with an agency or organization sponsoring foreign student exchanges under which the agency or organization ensures that Ohio residents enrolled in post-secondary educational institutions in the foreign country will pay tuition and fees at rates no higher than the rates charged to students who are residents of that country and under which the chancellor provides that rates for tuition and fees charged to a comparable number of students from the foreign country who are enrolled in state-assisted institutions of higher education in Ohio are to be no higher than the rates charged to students who are Ohio residents. Notwithstanding that an Ohio resident is enrolled in a post-secondary educational institution in a foreign country under one of these agreements, any such student who was previously enrolled in a state-assisted institution shall be counted as enrolled in such institution for state subsidy purposes in a manner prescribed by rules the chancellor shall adopt.
