The consitution takes a snapshot - are you a NBC at birth. The label is permanently affixed, even if a person renounces US citizenship. They were a NBC of the US, and are now a citizen of another country.

Yes, the criterion of "NBC" relates to one's status at birth - but babies are not eligible to be elected President, nor are 35-year-olds who have since renounced their U.S. citizenship.

By the way, re. "snapshot:" There is a third requirement for eligibility: Residency for at least 14 years.

It is a quirk of the constitution, that it does not express in words, for presidential qualification, that a person remain a citizen of only the US from birth until taking office. Intuitively, that is the intention, as the objective is to minimize doubt that the person has undivided loyalty.
