It seems like you are somewhere along in this process.
Can you comment on how many documents do you need documents for?
What kind of documentation is required to prove that you are a decendant?
ETA:
My grandparents are from Khust, Satmar, Sighet, and Veretzky.
Due to the information you provided about your ancestor, we would like to point out again the prerequisites for being eligible under the new law:
You must be a descendant of former Austrian citizens or persons who were citizens of successor states of the former Austro-Hungarian Monarchy or stateless at the time, but had their residence within the borders of the present Republic of Austria, and who were forced to flee from the territory of today’s Austria before May 15, 1955, because they had to fear or suffered persecution by the NSDAP (National Socialist German Worker’s Party) or other authorities of the so-called “Third Reich” or because they had to fear or suffered persecution because of defending the democratic Republic of Austria
Since your ancestor seemingly never lived on the territory of the present Republic of Austria, please recheck the respective prerequisites above.
