expats = migrants from the 'elite' class. educated, wealthy, well-connected etc. most often referred to persons from so called '1st/2nd world' countries.
immigrants = migrants from the 'cattle' class. not-so-rich, varied education, mostly non-caucasians. most often referred to persons from so called '3rd world' countries.
