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 only to children who would be otherwise stateless. It requires the possibility of naturalisation, and provides that the period of residence required for eligibility cannot be more than ten years lawful and habitual residence. It also requires to "facilitate" the acquisition of nationality by certain persons, including spouses of nationals, children of its nationals born abroad, children one of whose parents has acquired the nationality, children adopted by a national, persons lawfully and habitually resident for a period before the age of eighteen, and stateless persons and refugees lawfully and habitually resident on its territory.
