Well, technically ...those who are born here, are not immigrants.

The term in the U. S. Constitution about 'natural born' citizens ...is also a qualification for the President of our country, it seems, for the purpose of avoiding mixed loyalties.

My brothers, sister, and I ...all went to Michigan State University.  We all still cheer on the Spartans in collegiate sports ...yet, our degree of loyalty varies.  One of my brothers first met his present wife at college. Through the years, their home has been filled with Spartan paraphernalia ...and their children now go to Michigan State University.  All this is seemingly a result of two parents who graduated from the same college. 

It is common to have loyalty to where we have come from.  Yet again, we can attempt to slant definitions and standards to mean what we want them to mean.  It would seem inaccurate for me to say, but I could see some residents of our country saying that a natural born citizen is one who comes about by a natural birth ...where the mom chooses not to use drugs to reduce pain or for the purpose of quickening the birth.
