A large majority of Germany's 2.5 million repatriates or "Aussiedler" -- immigrants granted citizenship on the basis of their German ancestry -- come from the Soviet Union's successor states, mostly Russia and Kazakhstan. They are ethnic Germans from the Volga region and Crimea, deported by Josef Stalin in 1942 under gruesome conditions to Central Asia and Siberia. Fewer are arriving each year -- with 70,000 new repatriates in 2003 compared to a record 397,000 in 1993. But German authorities argue that despite decreasing numbers, their integration is becoming more difficult, because most of the latest arrivals speak no German. Now, Germany is introducing tougher rules in 2005 to limit entry to people who actually master the language. In the first of a two-part series about the challenges faced by repatriates in Germany, RFE/RL correspondent Sophie Lambroschini reports on how Russians and Kazakhs are adjusting to life in Wittstock, a small town in former East Germany.
