It is assumed the Congressional certification of votes cast by the Electoral College of the United States – occurring after the third day of January following the swearing-in of the new Congress, per provisions of the Twelfth Amendment – unambiguously confirms the successful candidate as the official "president-elect" under the U.S. Constitution.

A natural-born-citizen clause is a provision in some constitutions that certain officers, usually the head of state, must be "natural-born" citizens of that state, but there is no universally accepted meaning for the term natural-born. The constitutions of a number of countries contain such a clause but may define or interpret the term natural-born citizen differently. Many countries specify citizenship since birth as a requirement to hold certain offices. This is often described using the natural born phraseology and sometimes further qualified as requiring physical birth within the country's territory and/or requiring that one or both natural parents be a citizen of the country at the time of birth.
