As for any other citizenship process, the applicants are required to have no serious criminal convictions to pass the due diligence.
Applicants must present proof that they or their parents (or grandparents) resided in Austria and were persecuted. In addition, a connection must be demonstrated between extended family members and the family member who was the victim of the persecution.
In 2019, the Austrian Parliament passed an amendment to the nationality law, in order to facilitate the acquisition of citizenship for Holocaust survivors and their descendants. Eligible applicants include:
all former Austrian citizens and citizens of successor states of the former Austro-Hungarian Monarchy (or stateless at the time, but who had their residence in Austria)
descendants in the direct descending line (children, grandchildren, greatgrandchildren) of the persecuted person
To apply for the citizenship, applicants need proof that at least one of their ancestors was a Polish citizen and proof of family ties with the Polish family member.
Polish and Austrian citizenship laws allow descendants of victims of the Holocaust to obtain nationality with no limit to the number of generations that separate the applicant from their ancestors. Polish citizenship and nationality law is set out in the Polish Citizenship Act of 2009, which became law in its entirety in 2012, and it includes granting citizenship to Holocaust, WWII and the communist period victims.
