Here is the citation to the CRS analysis.
Would you also like the citation to the Lynch case, that is a case used as precedent to define “natural born”?
It’s easy to find, though.
“^ “Qualifications for President and the ‘Natural Born’ Citizenship Eligibility Requirement”. Congressional Research Service report. Federation of American Scientists. November 14, 2011. p. 2. Retrieved February 25, 2012. “In addition to historical and textual analysis, numerous holdings and references in federal (and state) cases for more than a century have clearly indicated that those born in the United States and subject to its jurisdiction (i.e., not born to foreign diplomats or occupying military forces), even to alien parents, are citizens ‘at birth’ or ‘by birth,’ and are ‘natural born,’ as opposed to ‘naturalized,’ U.S. citizens. There is no provision in the Constitution and no controlling American case law to support a contention that the citizenship of one’s parents governs the eligibility of a native born U.S. citizen to be President.”
