No automatic citizenship for kids born in U.S. to illegal immigrants article

Kids who are born in USA don't get OCI, they get only PIO card
even if you get OCI, you are not allowed to buy a agriculture land and occupy a public office, its just kind of visa without expiry date
and PIO card is valid for 15 yrs and if you want to stay in india for more then 6 months you need to report at nearest police station
my second one is just a example, even in japan, singapore, sweden, kids get based on what their parents have
