Your opinion is noted but it is not in harmony with the meaning of "... and subject to the jurisdiction thereof..." as the words were understood by those who framed the amendment and helped to ratify it, e.g. ,
John A. Bingham, considered the architect of the 14th Amendment, remarks on the intended meaning of “jurisdiction” as it appears in the amendment:
“I find no fault with the introductory clause, which is simply declaratory of what is written in the Constitution, that every human being born within the jurisdiction of the United States of parents not owing allegiance to any foreign sovereignty is, in the language of your Constitution itself, a natural born citizen…” Congressional Globe, 39th Congress (March 9th,1866)
On May 30th, of the 14th Amendment debates Senator Trumbull states:
“The provision is, that “all persons born in the United States, and subject to the jurisdiction thereof, are citizens.” That means “subject to the complete jurisdiction thereof.” . . . “What do we mean by “subject to the jurisdiction of the United States?” Not owing allegiance to anybody else. That is what it means….“It cannot be said of any Indian who owes allegiance, partial allegiance if you please, to some other Government that he is “subject to the jurisdiction of the United States” … It is only those persons who come completely within our jurisdiction, who are subject to our laws, that we think of making citizens; and there can be no objection to the proposition that such persons should be citizens." see: Cong. Globe 39th Congress, page 2893, 1st and 2nd columns
Mr. JOHNSON then rises to say: “…there is no definition in the Constitution as it now stands as to citizenship. Who is a citizen of the United States is an open question….there is no definition as to how citizenship can exist in the United States except through the medium of a citizenship in a State… “Now, all that this amendment provides is, that all persons born in the United States and not subject to some foreign Power–for that, no doubt, is the meaning of the committee who have brought the matter before us–shall be considered as citizens of the United States.” …he then continues “…the amendment says that citizenship may depend upon birth, and I know of no better way to give rise to citizenship than the fact of birth within the territory of the United States, born of parents who at the time were subject to the authority of the United States.”.”___ Cong. Globe. Page 2893 2nd dolumn, halfway down
Mr. HOWARD later follows up with regard to the meaning of “jurisdiction” by saying: “I concur entirely with the honorable Senator from Illinois, in holding that the word “jurisdiction,” as here employed, ought to be construed as to imply a full and complete jurisdiction on the part of the United States, coextensive in all respects with the constitutional power of the United States, whether exercised by Congress, by the executive, or by the judicial department; that is to say, the same jurisdiction in extent and quality as applies to every citizen of the United States now.” SEE: Cong.Globe, 39th Congress, page 2895, middle column
And in IN RE SLAUGHTER-HOUSE CASES, 83 U.S. 36 (1872) with regard to the phrase “subject to the jurisdiction thereof” the SCOTUS emphatically states:
“That its main purpose was to establish the citizenship of the negro can admit of no doubt. The phrase, subject to its jurisdiction’ was intended to exclude from its operation children of ministers, consuls, and citizens or subjects of foreign States born within the United States.”
And then in 1884, the Supreme Court once again echoes the intentions for which “and subject to the jurisdiction thereof” was written into the 14th Amendment:
'This section contemplates two sources of citizenship, and two sources only,-birth and naturalization. The persons declared to be citizens are ‘all persons born or naturalized in the United States, and subject to the jurisdiction thereof.’ The evident meaning of these last words is, not merely subject in some respect or degree to the jurisdiction of the United States,but completely subject to their political jurisdiction, and owing them direct and immediate allegiance.”_ Elk v. Wilkins, 112 U.S. 101 (1884)
And a D.C. Federal District Court once again echoes the intentions for which “and subject to the jurisdiction thereof” was written into the 14th Amendment as found in Elk v. Wilkins, in Tuaua v. United States, No. 13-5272 (D.C. Cir. 2015),
The Court, in 2015, while expounding upon jus soli writes the following:
"And even assuming the framers intended the Citizenship Clause to constitutionally codify jus soli principles, birthright citizenship does not simply follow the flag. Since its conception jus soli has incorporated a requirement of allegiance to the sovereign. To the extent jus soli is adopted into the Fourteenth Amendment, the concept of allegiance is manifested by the Citizenship Clause’s mandate that birthright citizens not merely be born within the territorial boundaries of the United States but also “subject to the jurisdiction thereof,” U.S. Const. amend. XIV, § 1, cl. 1; see Wong Kim Ark, 169 U.S. at 655, 18 S.Ct. 456 (“The principle embraced all persons born within the king’s allegiance, and subject to his protection… Children, born in England, of aliens, were natural-born subjects. But the children, born within the realm, of foreign ambassadors, or the children of alien enemies, born during and within their hostile occupation of part of the king’s dominions, were not natural-born subjects, because not born within the allegiance, the obedience, or the power, or, as would be said at this day, within the jurisdiction, of the king.”).
Appellants would find any allegiance requirement of no moment because, as non-citizen nationals, American Samoans already “owe permanent allegiance to the United States.” 8 U.S.C. § 1101(a)(22); see also Sailor’s Snug Harbor, 28 U.S. at 155 (“[A]llegiance is nothing more than the tie or duty of obedience of a subject to the sovereign under whose protection he is; and allegiance by birth, is that which arises from being born within the dominions and under the protection of a particular sovereign.”). Yet, within the context of the Citizenship Clause, “[t]he evident meaning of the … words [“subject to the jurisdiction thereof”] is, not merely subject in some respect or degree to the jurisdiction of the United States, but completely subject to their political jurisdiction, and owing them direct and immediate allegiance.” Elk v. Wilkins, 112 U.S. 94, 102, 5 S.Ct. 41, 28 L.Ed. 643 (1884)(emphasis added).
A child born on American soil to an illegal entrant foreign national does not meet the qualifier "...and subject to the jurisdiction thereof..." as the wording was understood by those who framed and helped to ratify the amendment.
Current policy, and not statutory law, is recognizing the offspring of an illegal entrant foreign national born on American soil as a U. S. citizens upon their birth. If you can find a statutory law to the contrary, quote its wording and give its citation.
The fact is, Trump can change the above mentioned "policy" with the stroke of his pen.
