How does the U.S. government define orphan?
Under U.S. immigration law, a foreign-born child is an orphan if he or she does not have any parents because of the death or disappearance of, abandonment or desertion by, or separation or loss from, both parents. A foreign-born child is also an orphan if his or her sole or surviving parent is incapable of providing care of the child and has, in writing, irrevocably released the child for emigration and adoption. For such a child to gain immigration benefits, an orphan petition must be filed before his or her 16th birthday. An orphan petition may be filed before the child’s 18th birthday, if the child is a natural sibling of an orphan or adopted child, and is adopted with or after that child, by the same adoptive parents.
