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 (jus soli) and/or requiring that one or both natural parents be a citizen of the country at the time of birth (jus sanguinis).
