Article 6 relates to the acquisition of nationality. It provides for nationality to be acquired at birth by descent from either parent to those born within the territory of the state. (States may exclude partially or fully children born abroad). It also provides for nationality by virtue of birth in the territory of state; however, states may limit this to only children who would be otherwise stateless.

It also provides for the possibility of loss of nationality for nationals habitually residing abroad. Finally, it provides loss of nationality for "conduct seriously prejudicial to the vital interests of the State Party".
