New AP entry
The Associated Press Stylebook has added an entry on illegal immigrant: Used to describe those who have entered the country illegally, it is the preferred term, rather than illegal alien or undocumented worker.
I know of a couple of papers that call for "undocumented worker." I like "illegal alien" much more and am glad AP went this way. (What if that undocumented worker isn't a worker? And exactly which documents must they be missing to remain undocumented?)
