What are the major challenges for Ukrainians arriving in Germany

Russia's invasion of Ukraine triggered a sudden and massive humanitarian exodus.
Since February, more than one million Ukrainian men, women and children have registered with authorities in Germany.
Now, a groundbreaking multi-year study is trying to document what they've been through.
Researchers have interviewed thousands of Ukrainian refugees who are now in Germany. They're trying to gain insights into the challenges of integration - such as the struggle to access services and to find school places for children - and they're documenting the psychological impact of these experiences.
