Blackstone discussed English law, the 14th ammendment says that the parents must be under US jurisdiction, which by treaty, requires the agreement contained in the visa application.

Blackstone discussed English law, the 14th ammendment says that the parents must be under US jurisdiction...

I don't know what Fourteenth Amendment you're reading, but the one in my copy of the Constitution of the United States says absolutely nothing about parents. It only refers to the person born or naturalized. To wit, "All persons born or naturalized in the United States and subject to the jurisdiction thereof..."

Absolutely nothing about the status of parents.

As with Blackstone, you seem to be imagining parents where none exist.

"...the 14th ammendment says that the parents must be under US jurisdiction, which by treaty, requires the agreement contained in the visa application."

As previously explained, this is false. No alien gets to choose whether they are under US jurisdiction. "Under the jurisdiction" is defined below.

United States v. Wong Kim Ark, 169 U.S. 649 (1898)

"It thus clearly appears that, by the law of England for the last three centuries, beginning before the settlement of this country and continuing to the present day, aliens, while residing in the dominions possessed by the Crown of England, were within the allegiance, the obedience, the faith or loyalty, the protection, the power, the jurisdiction of the English Sovereign, and therefore every child born in England of alien parents was a natural-born subject unless the child of an ambassador or other diplomatic agent of a foreign State or of an alien enemy in hostile occupation of the place where the child was born."
