An important point-most victims and survivors were not German; they were from Central and Eastern Europe and would have had no ties to Germany. So you have people from many areas with different options and different situations back where they came from and where in Germany or Eastern Europe you were at war's end. To use two extreme examples, a Danish Jew who had survived by being kept from going to the death camps and whose property had been secured by neighbors and a Ukrainian Jew who had been through the worst of the system but survived and whose town had been destroyed and been overtaken by neighbors who didn't want him back have very different options.

Probably the biggest factor determining your future is whether you'll suffer the additional misfortune of becoming stateless. If you come from Western Europe, you'll likely have your citizenship restored, which allows you the option of returning home in peacetime. But very few of your family and friends will be alive, and in most cases any prewar property and wealth you might have had will be gone. Unless you're from France, where a substantial Jewish community did survive the war, you'll eventually voluntarily emigrate to an Allied country.

If you're Eastern European, like a majority of survivors--about 230,000 people--you'll probably end up a "Displaced Person" after the war, de facto stripped of citizenship by your own country. (Poland was the worst offender: don't try to return there or you'll face summary execution.) Ultimately, U.S. Holocaust Memorial Museum stats say 80,000 Displaced Persons were allowed into the United States, and 20,000 into Commonwealth countries, particularly Canada and South Africa.

If you don't get to be in one of those cohorts, then you'll be one of the last 130,000 Displaced Persons trying to emigrate to British Palestine--and in a supreme historical irony, you might be fighting against Allied British soldiers in the Israeli Revolution just a few years later.

Depends on many factors, most important of which would be your country of origin. Were you a German Jew hiding throughout the whole war? Were you from another European country and were brought to one of German concentration camps? All of this would heavily influence your post war options.

Could you please specify what exactly you would like to know about post-war germany? Is it about the political situation, culture and society, legal situation?
