Watchdog groups say up to 400,000 children are born in the United States to illegal immigrants each year.
If they are born on U.S. soil, they are entitled to citizenship under an interpretation of the 14th Amendment.
This is where the fuzziness of the anchor baby interpretation comes in. Children of non-citizens who are born here can petition for legal status for their parents when they turn 21, which critics of the law say provides incentive for people to try to cross illegally into the United States in order to give birth.
There is legislation, which has stalled in Congress, that would “close a loophole” in the 14th Amendment, “by clarifying that birthright citizenship is only given to the children of U.S. citizens and legal resident aliens.”
