In general there are three categories of citizens abroad: firstly, citizens of a State may be abroad on the day of the election for business or personal reasons; secondly, there are citizens, who, for academic or employment purposes, spend a definite and temporary amount of time in another country, where they will reside for a given period; lastly, the third category comprises citizens residing abroad for a much longer period of time, who may sometimes have double nationality and who settle down in the host country in a more permanent manner.
