According to a report by Público, the Israeli Community of Porto asked the central services of the Institute of Registries and Notaries to give priority treatment to the Roman Abramovich case.

The Israeli Community of Porto (CIP) is alleged to have pressured the Central Registry Office to urgently naturalise Roman Abramovich: in an email sent on February 3, 2021 to Maria de Lurdes Serrano, director of the Central Registry Office, the Israeli Community of Porto invoked "reasons of national interest" that "involve the Government itself" to ask that his process be considered a priority, writes Público.

The process of attributing Portuguese nationality to the billionaire entered the Central Registries on October 14, 2020 and, until February of the following year, did not register any diligence, as the central service of the Institute of Registries and Notaries had received tens of thousands identical of requests.

According to the newspaper, CIP's management decided to request in the aforementioned email - for which confidentiality was requested - that an "urgent declaration" be made for that process or, alternatively, that it be transferred to the Conservatória do Porto where, according to CIP, the procedure would take around 10 months, unlike in Lisbon, where it could take up to 30 months.

In this letter, the Porto Jewish community, one of those that received from the Portuguese State the task of certifying the descendants of Sephardic Jews, even mentioned the name of the former Minister of Economy, Pedro Siza Vieira, with whom they had already met "with a view to possible investments in Portugal by Jews of Portuguese origin". CIP also forwarded to Central Registries a letter from B'nai B'rith International, the largest and oldest Jewish community in the world, signed by the organization's president, Charles O. Kaufman, underlining that "we are indebted to Roman Abramovich, Michael Kadoorie and Jacob Safra as benefactors for our community in Portugal".

The director of the Conservatória dos Registos Centrales, responded to the CIP email assuring that Abramovich's request would not take more than ten months to complete and determined that the process became urgent. Abramovich's naturalization application was eventually granted on April 13 by the former Secretary of State for Justice, Anabela Pedroso, and Portuguese nationality was granted on April 30, less than three months after the e-mail was sent by the Porto Jewish community.
