s much as I sympathise with the parents for their kids getting refused to land in India, I should point out, Mumbai officials did the right thing. Whether it is a white skin or brown skin a law is a law is a law...
The couple forgot(or did not care) to carry the PIO cards of their kids and they blame officials for not bending the law to give permission to enter the country?!
I would like to ask them not to take the green card and ask the same to US immigration officials. Here they wouldn't have dared to approach an US immigration officer with that kind of request.
It is a same pitiful approach of doing everything systematically or legally when you are outside of India and when you enter the country, you think you can talk into officials and make the law flexible to your cause...
