A deputy prime minister said in December that Poland was home to more than 2 million Ukrainians after many who had fled Russia's invasion moved on to other countries or decided to return to Ukraine.
In March last year, Poland enacted a measure to offer wide-ranging support to Ukrainians escaping the Russian invasion of their country, which began on February 24, 2022.
The measure grants them residence rights and ensures access to education, healthcare and social benefits.
Seventy-eight percent of Poles are in favour of accepting refugees from war-torn Ukraine, according to a survey published earlier this month.
