“In Anglo-American law today, deportation is a civil enactment imposed on persons who are neither native-born nor naturalized citizens. The alien is ordinarily, but not necessarily, returned to the country from which he came, usually because he has entered the deporting country illegally or without proper passport or visa. Aliens who become public charges, commit crimes involving moral turpitude, or engage in subversive activities can also be subjected to deportation proceedings. U.S. courts have shown leniency in circumstances in which families are split apart unjustifiably and left with no means of support.
Deportation differs from exclusion, extradition, and exile. Exclusion is the refusal by a governing authority to admit an alien. Extradition is the removal of a criminal to the country from which he has fled to avoid criminal prosecution or prison. Exile is a prolonged absence from one’s country, either voluntary or by direction of the sovereign.”July 20, 1998
