While it may be a good idea to allow dual citizenship to persons of Indian origin, Govt of India cannot allow persons holding Pakistani citizenship to get Indian citizenship as well. As on 15th. August 1947, all persons who opted to stay back in Pakistan were eligible to become Indian citizens, had they come into India. At this point in time to grant them Indian citizenship will be a disaster. Govt of India should clearly define the countries from where such persons are eligible. Same goes for the erstwhile East Pakistan, now Bangladesh. If this distinction is not adopted, it will be a national disaster !!
