3.5. Citizenship by Incorporation of Territory (Section 7)

If any foreign territory becomes a part of India, the Government of India, may by orders notified in the Official Gazette, specify the persons who shall be citizens of India by reasons of their connection with that territory, and those persons shall be citizens of India as from the date to be specified in the order. E.g. when Pondicherry became a part of India, people of Pondicherry became the citizens of India under the Citizenship (Pondicherry) Order, 1962, issued under the Citizenship Act, 1955.
