In 1933, the Salvadoran delegation to the Pan-American Union's Montevideo conference, Arturo R. Ávila and signed the Inter-American Convention on the Nationality of Women, which became effective in 1934, legally reserving limitations for modifications of their domestic naturalization law. That year, the legislature adopted the Migration Law of 1933 (Ley de Migración de 1933), which excluded from immigration blacks, Malays, Romani people and other Hungarians, as well as Arab, Lebanese, Palestinian, Syrian, Turkish, or any ethnic group generally associated with the former Ottoman Empire. The law also banned anarchists, communists, Jews, and Muslims and other groups which might pose a threat to the social order. The constitution of 1939, provided women and men equal ability for their children to receive their nationality and allowed Salvadoran women to retain their nationality unless they chose to nationalize in accord with their husbands' nationality.
