You know what first thing the parents would have done?
They would have called their friends and told.."U know, these stupid indians they don't even ask for the VISAs for US born kids."
Then you know what will happen, then 1000s of people will try to follow the same example to board the flights with kids without a valid VISA to india.
Good thing about this getting published on Rediff, is that next time people won't make that kind of stupid arrogant mistake of forgetting their VISA thinking they can rule the world with a green card.
