Its because of the British!!!!,, Indians fought so hard to get rid of them that becoming Indian was a matter of pride and priceless. The consitituion says it to that effect. However, these days of globalization, especially for Indians that rule is becoming obsolete to my opinion. NRI's are much more patriotic to their country of origin than the citizen's themselves.. Nevertheless, India should have the provision to reclaim back Indian nationality like Pakistan, Bangladesh or even U.K. to that matter!!
