A child born inside or outside the Vietnamese territory either of whose parents is a Vietnamese citizen and the other is a stateless person at the time of his/her birth or whose mother, at the time of his/her birth, is a Vietnamese citizen and whose father is unknown, has Vietnamese nationality.

2.
