According to the Portuguese law, the designation of Sephardic Jews refers to the descendants of the ancient Jews and traditional Jewish communities of the Iberian Peninsula. The presence of these communities in the Iberian Peninsula is very old, dating before the formation of the Iberian Christian kingdoms, as was the case with Portugal.
This law authorizes the exercise of the right of return for Sephardic Jews who are descendants of Portugal and who wish, through the acquisition of Portuguese nationality by naturalization, to exercise their rights and obligations.
The Government may grant citizenship through naturalization to the descendants of Sephardic Jews, when they fulfill the following requirements:
1. Are adult or emancipated under the law
2. Have not have been convicted, with final judgment of sentence for committing a crime punishable by a maximum prison sentence equal to or exceeding three years, under Portuguese law.
The request submitted by the interested or his lawyer is indicated and demonstrated the circumstances of belonging to a tradition of Sephardic community of Portuguese origin, in particular, family surnames, familiar language, direct descendants or family relationship in the collateral line of common parent from the Sephardic community of Portuguese origin.
