text: when deported, does that mean they can no longer ever return to the us? a nigerian associate was deported after committing a crime, does that mean he'll never be able to come back to the us, even though he served his time in a federal prison (18 months)? when you are deported, the judge that orders the deportation usually states the period of time that the person is not allowed to return to the u.s., depending on the laws that were broken that warranted such deportation.
