Cruz is a naturalized US citizen (8 U.S.C. § 1401(g))
If the red underlined “and” in subsection (3) is or should be construed as “or” then the question is: were his parents admitted for “permanent residence”? If yes then Cruz is in law a “natural born citizen” of Canada. If no then he is not a “natural born citizen” of Canada, although he may be a citizen under a different provision.
Fantastic.
