Syrian nationality law: Syrian nationality law is the law governing the acquisition, transmission and loss of Syrian citizenship.  Syrian citizenship is the status of being a citizen of the Republic of Syria and it can be obtained by birth or naturalisation.  The Syrian nationality is transmitted by paternity (father) (see Jus sanguinis).  Therefore, Syrian nationality is determined solely by the father's nationality, while the place of birth is irrelevant.  In other words, birthright citizenship is not recognized since being born in Syria does not grant an automatic right to become a national.  In most cases, individuals are deemed to be Syrian nationals regardless of whether they are born inside or outside Syria as long as their father holds Syrian nationality.
