BRITISH NATIONALITY

Section 16 of the British Nationality Act 1981 (which comes into force on 1st January 1983—see S.I. 1982/933) provides, inter alia, that a person born outside the dependent territories after the commencement of the Act is a British Dependent Territories citizen if at the time of the birth his father or mother is such a citizen and is serving outside the dependent territories in service designated by the Secretary of State, recruitment for that service having taken place in a dependent territory. This Order designates various types of service for the purposes of this provision.
