Salvadoran nationality law is regulated by the Constitution; the Legislative Decree 2772, commonly known as the 1933 Law on Migration, and its revisions; and the 1986 Law on Foreigner Issues.[1] These laws determine who is, or is eligible to be, a citizen of El Salvador. The legal means to acquire nationality and formal membership in a nation differ from the relationship of rights and obligations between a national and the nation, known as citizenship.[2][3][4] Salvadoran nationality is typically obtained either on the principle of jus soli, i.e. by birth in El Salvador; or under the rules of jus sanguinis, i.e. by birth abroad to a parent with Salvadoran nationality. It can also be granted to a citizen of any Central American state, or a permanent resident who has lived in the country for a given period of time through naturalization.[5]
