 Yehuda Bauer says that the number of visas must have been close to 10,000 and that is the number of refugees who actually reached Portugal in the summer of 1940.But he adds that of these 10,000 "“not all of them received visas from Mendes, but a very high proportion must have”".To reach a more accurate figure, the visas granted by the Portuguese consulates in Rotterdam, Den Hague, Antwerp, Paris, Toulouse, Berlin, Geneva, and other cities would need to be counted, according to Yad Vashem historian Avraham Milgram in a study from 1999 published by the Shoah Resource Center An analysis of the list of visas granted by Sousa Mendes to Jews and non-Jews in May and June 1940 indicates that the number of visas granted by the consul was lower than the numbers mentioned in the literature, raising questions about Portugal and the entry of Jewish refugees.
