Okoyong Past Students Association(OPSA) USA was formed in the early 1980s by a group of dedicated past students who saw a genuine need to create a forum, where past students of Queen of the Rosary College, Okoyong could express their practical commitment to their Alma Mater and each other.

In Oct 2014 it was renamed United OPSA USA under the auspices of the most reverend, Doctor Andrew Nkea, the Bishop of Mamfe and  the current proprietor of the school. United Okoyong Past Students Association (United OPSA-USA) is an alumni association with members who are all past students of Queen of the Rosary College (QRC) in Okoyong-Mamfe, Cameroon (Africa).

This 501(c) 3 non-Profit Organization was established for the purpose of empowering its members as well as Cameroonian youths, by fostering academic, economic, spiritual and social development of the girl child enrolled in QRC, Okoyong. United OPSA-USA is a branch of the umbrella organ OPSA General headquartered in Cameroon.
