Neither CIU nor WIU have ever been accredited by a regional accrediting association in the United States. WIU does not teach any courses or award any degrees in the United States.
WIU has had operations in other countries: Brazil, Canada, China, Estonia, Ghana, Hong Kong, Nigeria, Russia, Singapore, Trinidad & Tobago, and Ukraine*.
*A degree awarded by the Ukrainian-American Humanitarian Institute “Wisconsin International University" (USA) in Ukraine indicated recognition by the Accrediting Commission International (ACI), Arkansas. ACI does not appear on the list of recognized accrediting bodies published by the Council for Higher Education Accreditation (CHEA) of the U.S. Department of Education. Despite the Ukrainian institution's accreditation by the Ukrainian Ministry of Education, a standard national diploma was not issued for this degree, rendering it unverifiable through the Ukrainian OSVITA verification database.
