By Birth – The most important mode of acquiring nationality is by birth. Nationality is conferred to a person by many States on the basis of birth. All those persons who take birth within the territorial limit of a State acquire the nationality of the State. This principle is called jus soli. India also provides citizenship by birth under S.3 of the Indian Citizenship Act.
By Naturalization – The next mode of acquiring a Nationality is by naturalization. A person requires nationality at birth. But, his nationality may later on change.
When the nationality of a person changes subsequently, and he acquires the nationality of some other State, the process of acquisition is called naturalization. A person may acquire nationality through naturalization in various ways.
There are six ways which are as follows –
(1) Through marriage. For example, wife assuming her husband’s nationality.
(4) Acquisition of domicile,
(5) Appointment as Government official
(6) Grant on the application of the state. Adoption of the child by parents who are nationals of the other States also entitled the children to acquire the nationality of his parents.
Section 6 of the Indian Citizenship Act 1955 provides that a person may acquire citizenship by naturalization upon fulfillment of certain conditions.
By Resumption – The next mode of acquiring Nationality is by resumption. Sometimes a person may lose his nationality because of certain reasons. But later he may resume, recover his original nationality after fulfilling certain conditions. Section 20 of the Citizenship rules 1956 provides a procedure for the restoration of nationality.
By Subjugation – The fourth mode of acquiring nationality is subjugation. Section 7 of the Indian Citizenship Act 1955 Lays down that if any territory becomes a part of India those persons from such territory shall automatically become Citizen of India.
By Cession – The fifth mode of acquiring Nationality is Cession. When a part of the territory of a state is ceded to another State. All Nationals of the former acquires the nationality of the latter State.
By Option – The Sixth mode of acquiring Nationality is by Option. When a state is proportioned into two or more States, the nationals of the former state have an option to become the nationals of any of the successor States. The same principle applies in the case of an exchange of territory.
By Registration – A person may acquire the nationality of a State through Registration. The process of registration may be different from one state to another depending upon the laws of that State. It takes place when a person becomes the subject of a state to which he was before an alien.
Modes of Loss of Nationality
By Release: Some States, such as Germany., Law provides that the citizens may lose their nationality by release. In the loss of nationality by release it is necessary to submit an application for the same. If the Application is accepted, the person concerned is released from the nationality of the State concerned.
Deprivation: The certain States have framed some municipal laws the breach of which by its nationals results in the deprivation of their nationality. Under the American laws, service in the armed forces of a foreign state also results in deprivation of citizenship.
Expiration: In certain States, on account of legislation citizenship expires due to a long stay abroad. A naturalist American citizen loses his nationality by having s continuance residence for three years in the territory of a foreign state of which he was formerly a national or in which the place of his birth is situated.
Renunciation: A person may also renounce his nationality. The need for renunciation arises when a person acquires the nationality of more than one State. In such a condition he has to make a choice as to of which country he will remain national. Finally, he has to renounce the nationality of one State.
In the case of double nationality of children, the municipal laws of certain States like Great Britain give them a right on coming of age to declare whether they wish to cease to be citizens of one State.
The British Nationality Act of 1948 permits such a child to make a declaration of the renunciation of citizenship of the United Kingdom, but the registration of such a declaration may be withheld by the Secretary of State if made during any war in which the United Kingdom be engaged.
Substitution: Some States provide for the substitution of nationality. According to this principle, a person may get the nationality of a state in place of the nationality of another State. This is called nationality by substitution whereby he loses nationality of state and acquires the nationality of another State. The British Nationality Act 1948, does not automatically entail the loss of British nationality on the naturalisation of a British subject in a Foreign State. The United States nationality Act of 1952, however, entails the loss of American nationality on the voluntary naturalisation of an American National in a foreign country.
In certain States, the law provides that if the national of that State without seeking permission of the government obtain employment in another State, then he may be deprived of his nationality
A stateless person is someone who is not recognised as a national by any state. They have no nationality or citizenship and are unprotected by national legislation, leaving them vulnerable in ways that most of us never have to consider.
They are often not permitted to attend school or university, may be prohibited from getting married, and may not be able to register births and deaths. Stateless people can neither vote nor access the national justice system.
- States may simply cease to exist when individuals fail to get citizenship in their successor states;
- political considerations may dictate changes in the way that citizenship laws are applied;
- unethnic minority may be persecuted by being denied citizenship;
- a group may live in frontier areas and frequently cross borders, causing states on both sides of the border to deny them citizenship.
Also, there are individuals who become stateless due to personal circumstances, rather than persecution of a group to which they belong. Statelessness can arise from legal differences between countries, people renouncing one nationality without having acquired another or even, more simply, from failure to register the birth of a child.
Also, small islands which, condemned by a changing climate to be swallowed by the sea, will see their entire populations become stateless.
Nationality and India
The conferment of a person, as a citizen of India, is governed by Articles 5 to 11 (Part II) of the Constitution of India.
The legislation related to this matter is the Citizenship Act 1955, which has been amended by the Citizenship (Amendment) Act 1986, the Citizenship (Amendment) Act 1992, the Citizenship (Amendment) Act 2003,
The Citizenship (Amendment) Act, 2005 and Citizenship (Amendment) Act, 2015. Indian nationality law largely follows the “jus sanguinis” (citizenship by right of blood).
