The main reason for the Ukrainians is job search. Last year, citizens of Ukraine and Russia received most of the permissions for residence. In total, 3.1 million of such documents were issued.
According to the report of Eurostat, about 662,000 Ukrainians, or some 21 percent out of the total population of foreigners, received a primary (issued for the first time) residence permits in 2017 in the EU, 88 percent of which were issued in Poland.
While, Syrians received around 223,000 of such permits, mostly in Germany.
The main reason the Ukrainians received such documents was employment (more than 580,000 people in 2017). For Syrians, the reason concerns the humanitarian aspect.
According to the reports of the European Council, the largest number of the people who were forcefully kept in the region as 'modern slaves', was recorded in Russia. The number made approximately about eight million people.
