Warsaw - Poles made up the largest immigrant group in the European Union, followed by Romanians and Moroccans, an EU report said Tuesday.
Out of some 3 million immigrants that settled in the EU, some 290,000 were Poles, said the Eurostat statistics based on 2006.
Some 2 million Poles went to work in other EU countries - notably Britain and Ireland - since Poland joined the European Union in 2004.
Poles working abroad have contributed to the ex-communist nation's prosperity, sending home more than 8 billion dollars in 2007 while helping to cut the jobless rate.
