Well:
The Congressional Research Service concluded in 2011:
“The weight of legal and historical authority indicates that the term ‘natural born’ citizen would mean a person who is entitled to U.S. citizenship ‘by birth’ or ‘at birth,’ either by being born ‘in’ the United States and under its jurisdiction, even those born to alien parents; The predominant legal scholarship holds that the term natural born citizen applies, quite simply, to anyone who is a U.S. citizen at birth, or by birth, and does not have to go through the naturalization process. The child of parents who are U.S. citizens, regardless of whether he or she is born abroad, fits into the category under most modern interpretations.”

Those CRS Memos were written by request of Nancy Pelosi and others in Congressional leadership to give Obama cover and to provide the Members of Congress with unified talking points as to what to tell their constituents in answer to all the phone calls, letters, and email they were receiving asking about Obama’s lack of Article II constitutional eligibility, and that Congress was doing nothing about it during the election and afterwards (impeachment or a quo warranto action by Congress, etc.).
The first one was written in secret and about a year later it was leaked to Attorney Mario Apuzzo who published it to the world in his blog. Then about three days later WorldNet Daily picking up the new from Apuzzo’s blog, did a major story about it.
I coincidentally was in Atty Apuzzo’s office for a meeting with him that day when the copy of the first CRS Memo re Obama and the nbC issue was delivered to Atty Apuzzo that day by express delivery service from a member of a U.S. Senator’s staff who wanted it to be public information instead, of a secret internal memo and talking point document: http://puzo1.blogspot.com/2010/11/members-of-congress-memo-what-to-tell.html
In those CRS Memos, the very politically biased lawyers carefully parsed selected items of history with generous use of the ellipses in quotes in order to make Obama eligible, when he was not.
Read this excellent legal analysis by another lawyer and scholar taking apart the legal tripe and quotes with omissions of key clauses in various parts of the CRS Memos: https://www.thepostemail.com/2011/05/29/bombshell-second-crs-memo-covering-for-obamas-ineligibility-not-released-to-the-public-until-now/
