That is the law by 14th Admendment of Constitution in the USA, but is increasing being called into question. See: http://www.bloomberg.com/news/2010-...park-clash-on-u-s-citizenship-procedures.html Recently Israel expelled 400 children born in Israel. Their non-Jewish parents were there legally on multi-year work permits, but those permits expired. Bedouins, all of whom were born in land now Israel and many except the oldest, born in the state of Israel have no rights as citizens (unless they join the army). - They are confined to one of three concentration camp cities. Only 30 nations grant citizenship to anyone who is born inside their country. Do you think the US should continue to do this? If you vote no, what would be the basis of granting citizenship? I voted "yes" mainly because I can not think of a better way to determine who is a citizen. But there is a growing problem that requires better control of the borders.
