The writers of the fourteenth in private correspondence and interviews explicitly state that it applies only to the children of those who where once held as slaves in this nation. I doubt that there are any left that meet those requirements.
Any child born of illegal parent or parents is also an illegal. If by hook or crook he or she stays through high school, maybe even college, tuff. they along with their parents should be deported.
Upon arrival in the country of origin of the parents, the child can report to the US embassy and barring a criminal record be put at the top of the list for entry to the US. Their having been here illegally will not be held against them but will be against their parents. They will then have to satisfy the same requirements as any other immigrant to become a citizen.
Their parents can not come here to visit. Nor can green cards be issued to relatives.
Any one saying that the fourteenth grants citizenship to any one born here is shilling for the progressives.
born in the US means US citizen.
That said, the law need to be changed. Constitution or mere law. The original reason for the 14th automatically granting citizenship is no longer present. It is also from an era where STATES controlled immigration.
