A British subject who, when in any foreign state and not under disability, by obtaining a certificate of naturalization or by any other voluntary and formal act, becomes naturalized therein, shall thenceforth be deemed to have ceased to be a British subject.
(1)Any person who by reason of his having been born within His Majesty's dominions and allegiance or on board a British ship is a natural-born British subject, but who at his birth or during his minority became under the law of any foreign state a subject also of that state, and is still such a subject, may, if of full age and not under disability, make a declaration of alienage, and on making the declaration shall cease to be a British subject.
(2)Any person who though born out of His Majesty's dominions is a natural-born British subject may, if of full age and not under disability, make a declaration of alienage, and on making the declaration shall cease to be a British subject.
Where His Majesty has entered into a convention with any foreign state to the effect that the subjects or citizens of that state to whom certificates of naturalization have been granted may divest themselves of their status as such subjects, it shall be lawful for His Majesty, by Order in Council, to declare that the convention has been entered into by His Majesty; and from and after the date of the Order any person having been originally a subject or citizen of the state therein referred to, who has been naturalized as a British subject, may, within the limit of time provided in the convention, make a declaration of alienage, and on his making the declaration he shall be regarded as an alien and as a subject of the state to which he originally belonged as aforesaid.
Where any British subject ceases to be a British subject, he shall not thereby be discharged from any obligation, duty or liability in respect of any act done before he ceased to be a British subject.
