A study recently released by the Israel Democracy Institute and Itim warns that over the next two decades, hundreds of thousands of Israeli citizens from the former Soviet Union or of Ethiopian descent may need to undergo a process to validate their Judaism.
The study showed an increase in the proportion of cases that ended with a ruling that the applicant was not Jewish, from 2.9 percent in 2011 to 6.1 percent in 2016 to 6.7 percent in 2017.
