What also needs clarification is the ‘jurisdictional’ status of minors and parents.
It has always been accepted that minors are under the jurisdiction of their parents unless legally ruled upon (orphans, fosters and adopted are all of legal status).
A minor is never an sovereign citizens until s/he comes of age (currently, 18).
They are under their parents jurisdiction who are held responsible for them.
At no time has this status been ruled upon nor even brought before the SCOTUS that I know of.
There have been case-by-case alterations (murder tried as an adult).
In a hyperbolic sense, if a child, born on US soil, is conferred full and sovereign US citizenship, then that child can enter into full and binding contracts (mortgages) at birth or any time following.
If this is first clarified then any minor born on US soil to foreign parents is subject to their (parents) jurisdiction.
Who, in turn, are subject to their country of origin.
I would postulate that if this is not adjudicated such that the current understanding of “birth-right” citizenship is not eliminated, the Federal Government would have no choice but to lay-claim to her own sovereign citizens while the parent(s) would be required to leave the US according to their passport/visa status.
If the United States can arrest the alien parents, place them in US court proceedings, take their stuff, and put them on plane to South Sudan, then a textualist would certainly say those alien parents are being subjected to US jurisdiction.
Don’t worry, Chief Justice John Robert’s will rule that since virtually all birthright citizenship Anchor Babies are on multiple forms of welfare, Birthright Citizenship is tax on the American people and thus 100% constitutional
