In September 2022, IAU relocated the Orange County Satellite Campus (IAUOC) to the City of Irvine. TIAU is a member of the Accreditation Council for Business Schools and Programs (ACBSP) and is currently seeking ACBSP accreditation for its business programs, as well as separate accreditation for its accounting program. ACBSP is a prominent accrediting body focused on business education.

Its mission is to foster a better future by promoting and recognizing excellence in business education through ongoing improvement efforts. ACBSP envisions a world where all quality business programs are accredited and committed to continuous enhancement. The council accredits business, accounting, and related programs across associate, bachelor's, master's, and doctoral levels. Recognized by the Council for Higher Education Accreditation (CHEA) in both 2001 and 2011, ACBSP was the first organization to provide specialized business accreditation at every degree level, including certificate programs. Currently, ACBSP accredits business programs at over 1,200 institutions in 60 countries.
