The analysis contains the evaluation of migration effects of labour from Central and Eastern European countries which became European Union member states in 2004, on old member's labour market. Particular emphasis was placed on evidence of the migration flows impact from the new EU member states on the labour market performances in the United Kingdom and Ireland, the countries which did not restrict the access of new member immigrants to their labour markets. The analysis was realized for the period of 2004 to 2008 when the migration inflow was the largest. The empirical literature suggests that the migration effects on unemployment and employment probabilities of natives are very small. The young and low skilled native workers are more affected by migration flows than other groups of workers. Also, most empirical studies show small negative wage effects of immigration. Although the results of public researches and econometric studies have shown the modest potential labour migration flows from new member states and the small potential effects on EU-15 labour market, twelve out of fifteen old member states decided to apply transitional arrangements. The evidence presented in the report of the European Commission pointed out positive EU labour market impact of modest inflow of immigrants from new member states. Sectoral and skill composition of immigrants from new member states suggests their complementary role on EU labour market. The majority of immigrants from new member states are men, aged between 18 and 34, mediumlevel of education. Most immigrants have been employed in service sector, manufacturing and construction. The high employment rate of immigrants from new member states (78%) and low unemployment rate (6%) in the post-enlargement period have confirmed positive migration impact on EU labour market performances. The unemployment effects of migration have been smaller than projected. The migration flows from new member states have resulted in negligible increase in EU-15 unemployment rate by 0.02-0.04% and decrease in native wages by 0.08%. In the second part of this paper the migration impact on labour market of the United Kingdom and Ireland is examined. The selective application of transitional measures across EU resulted in substantial diversion of migration flows toward the United Kingdom and Ireland. In the period of 2004-2008, Ireland accepted 448.000 immigrants from new member states and in the United Kingdom 926.000 immigrants %K migration flows %K labour market %K European Union %K unemployment %K wage %U http://www.doiserbia.nb.rs/img/doi/0038-982X/2011/0038-982X1102051P.pdf
