In which Part of the Constitution, details of citizenship are mentioned ?

The details of citizenship in the Indian Constitution are contained within Part II, covering Articles 5 to 11 [1][t1]. This part specifically identifies categories of persons who became citizens of India at the time of the Constitution's commencement on January 26, 1950 [c1][t4]. Article 5 deals with citizenship by domicile, while Articles 6 and 7 address the rights of persons who migrated from or to Pakistan [t1][t2]. Article 11 is particularly significant as it empowers the Parliament to regulate the right of citizenship by law, allowing for the enactment of legislation like the Citizenship Act of 1955 to handle acquisition and termination of citizenship after the commencement of the Constitution [c1][t3]. While Part I deals with the Union and its territory and Part III covers Fundamental Rights, Part II remains the dedicated section for constitutional provisions regarding citizenship [c1][t1].
