They provide the following information regarding accreditation:

“IUON has been chartered by the Federation of St. Kitts-Nevis to offer the Associate Degree and Bachelor of Science in Nursing Degree. IUON is fully accredited by the government of St. Kitts for the Associate Degree in Nursing and provisionally accredited for the Bachelors Degree in Nursing. IUON plans to obtain independent accreditation from U.S. boards of nursing and appropriate institutional accrediting bodies.

The U.S. institutions affiliated with IUON for the purpose of offering the last year of the ADN and BSN program are all fully accredited by the National League for Nursing Accrediting Commission (NLNAC), Commission on Collegiate Nursing Education (CCNE), the appropriate institutional accrediting bodies, and applicable state boards of nursing.” (http://www.iuon.org/WELCOME/ACCREDITATION/accreditation.html )

I suggest to contact them or AORN (http://www.aorn.org/ ) with you question.
