A couple of years ago I went to Indian consulate in New York City to acquire an Indian visitor Visa to follow an India Pak cricket game.
While I was walking towards the visa counter, I was intercepted by two pre-visa application screeners.
I was asked what nationality are you? "American" I replied.
Do you have any relationship with Pakistan? I said yes, my parents were born in Pakistan and I am a dual citizen.
Guess what I was told when my American passport was given back to me?
"You need to go a Pakistan consulate - denounce your dual Pakistani citizenship - bring us back a notarized copy of an official letter from the govt of Pakistan that you have denounced your citizenship AND ONLY THEN we may CONSIDER taking your application."
I said, "I am an American citizen who wants to travel to India to follow an India Pak cricket game"
In response to which, I was given a piece of paper that had this official policy which was something like this.
"If you, your father, your grand father, your grand mother (grand father's wife), your mother, your mother's mother, your mother's father, your spouse, your spouse's mother, your spouse's grand mother, your spouse's father or your spouse's grand father" was born in Pakistan, OR was born before 1947 in a part of India that is now Pakistan or Kashmir, then you are subject to bring a notarized copy of an official letter from the govt of Pakistan that you have no relationship to Pakistani citizenship."
I returned the paper to him and replied: "Mein tumharay visay pe pehshaab karta hoon"
