@amitkilhor Are you illiterate or pretending to be one? It doesn't say citizen. It says nationality. Even US issues passports to Nationals and non-citizens. There's a difference. Get some education, dumbo.
@abhishek Lol, you don't have any World knowledge. US grants passports non-citizens. Valid, legal passports to non-citizens. Just look it up. Passport is not a proof of citizenship, it is a travel document!
