Seems this article here:

Medical University of the Americas of Belize - Gone or in rest?, Belize News, San Pedro Sun

sheds some light on the situation. Both MUA-UK (if it ever existed) and MUA-Belize are now practically defunct. PL is currently being sued in NJ per the students lawsuits and from the rumors i've heard is still intent on starting another school somewhere in the Caribbeans.
