The Citizenship Act 1955 makes provision for renunciation of Indian citizenship.
If any citizen of India of full age and capacity, who is also a citizen or national of another country, makes a declaration renouncing his Indian Citizenship in the prescribed manner, the declaration shall be registered by the prescribed authority; and, upon such registration, that person shall cease to be a citizen of India subject to the provision that if any such declaration is made during any war in which India may be engaged, registration thereof shall be withheld until the Central Government otherwise directs.
Where a person ceases to be a citizen of India under sub-section upon making a declaration as provided above, every minor child of that person shall thereupon cease to be a citizen of India subject to the provision that any such child may, within one year after attaining full age, make a declaration that he wishes to resume Indian citizenship and shall thereupon again become a citizen of India.
For the purposes of the above provisions, any woman who is, or has been, married shall be deemed to be of full age.
It has been held that a person who gives up his claim to Indian citizenship cannot claim right of residence on the basis of his domicile.
