Article 5 of the Constitution of India deals with the citizenship of India. It states that at the commencement of the Constitution, every person who has his/her domicile in India and:

a) was born in India; or

b) either of whose parents was born in India; or

c) who has been ordinarily resident in India for not less than five years,

shall be a citizen of India.

This article lays down the basic criteria for determining the citizenship of India, which is based on birth and domicile. It establishes that a person who is born in India, or whose parents were born in India, or who has been residing in India for a certain period of time, is deemed to be an Indian citizen.

It is important to note that this provision only applies to persons who were citizens of India at the commencement of the Constitution. Subsequent changes have been made to Indian citizenship laws, including the enactment of the Citizenship Act, 1955, which defines who is a citizen of India and how citizenship can be acquired, lost, or renounced.
