Question special

The paper has defined offshore medical schools as for-profit institutions listed in the International Medical Education Directory located in the Caribbean or Belize educating primarily U.S. and Canadian students intending to return to North America to practice medicine. However, the fact remains that U.S.IMGs attend medical schools in other parts of the world as well, including Italy, Hungary, India, China, Thailand, Nepal, Mexico, among others. I wonder what is the rationale behind choosing only this sub-set of off-shore schools for this analysis and what would be the wider implications of including all the possible off-shore schools in such a discussion.
