A
foreign-born
resident of a
country. An alien can be in the country
legally (often to
work or seek an
education) and eventually seek
citizenship, if he or she lives there long enough, or they can be in the country
illegally (usually to work or visit
friends or
family), which means they may be
deported back to their
home nation, if caught.
Also, an
extraterrestrial, sent to our
planet to
abduct rubes in the woods, make
pretty patterns in
cornfields with their
UFOs,
kill all the
men, and
make wild nookie with the
women. We have only one
defense:
foil hats for
everyone!
