A new report in Bild newspaper says that 26% of Hartz-IV (long-term welfare) recipients are immigrants.
At the end of April, a total of 1.54 million foreigners received Hartz IV benefits.
This is 12.4% more than in 2015.
Meanwhile, the number of Germans receiving welfare fell by 5.2%.
Most immigrants receiving welfare came from Turkey, at 295,000, followed by Syrians at 242,000 and Poland with 92,000.
Germany has been plagued by a series of sexual assaults since opening its borders to refugees. German politicians have celebrated Germany's approach to refugees and immigrants as the creation of a so-called “supercultural” society.
It was revealed that refugees were caught committing nearly 70,000 crimes in only three months of 2016 alone.
