The amended law allows descendants of Jews who were expelled in the 16th century to become citizens if they "belong to a Sephardic community of Portuguese origin with ties to Portugal," according to José Oulman Carp, president of Lisbon's Jewish community. The website of the World Jewish Congress says that the Jewish Community of Lisbon is the organization that unites local communal groups of Lisbon and its environs, while the Jewish Community of Oporto is the organization that unites local communal groups of Oporto.
