More to the point, UHSA's own website is highly misleading about licensure -
University Of Health Sciences Antigua School of Medicine - Licenses in the United States
It lists some 30 states, including California, where it says its grads. have been licensed over the last 25 years.
Licensure in Ca. (and in all probability some other states on that list) will surely have been achieved either because of out-of-date requirements, reciprocal agreements or deception.
The OP, RoHudTuffy, is eager to remind us how financially successful the owner, Dr. A., has been. Clearly he did not achieve this great wealth by being scrupulously honest with his prospective customers. Although such transparency is probably too much to hope for from most Caribbean schools.
