most people here including me don't have enough faith in the percentage of people who will use this for the benefit of the motherland. unlike in china and russia where the percentage of people who will be traitors or just waste it is low, in india, there can be many factions who would just exploit it, waste it and achieve nothing productive for the country or even harm india in return from abroad. no hard feelings. just being honest.
we need an internal defacto and dejure system to first take care of every manner of traitor internally in our country first in order to then facilitate the dual citizenship plan.
What the heck does this have to do with dual citizens?
Those who want to harm India are not going to be anyways deterred by some stupid law. Bangladeshis live in India and possess Aadhar, Passport and what not. It only harms law abiding people who want to operate legally.
This is VERY VERY similar to situation during license raj. Government was very concerned that if given liberty, the industrialists etc will loot common people, corner markets and what not. There used to be 10 years waiting list to buy a scooter during those times. After liberalization of 90s if anything ownership of resources by common people has increased. The only one who were harmed by end of license raj were touts, middle men, beaurocrats etc. Those who used to take massive bribes.
This entire situation of citizenship is same: beaurocrats thinking that they are protecting their turf. Its ... nothing but they are harming law abiding people by kicking them out of India meanwhile massive amount of illegals are coming in to the country.
Remember, Kasab did not take any visa. Neither do infiltrators. Nor any bagladeshis.
Here is the kicker: A person can acquire citizenship of Australia or Canada and unless the person volunteerily tells Indian government about this, they have no way of even finding out.
