The aim of my diploma thesis is to chart the situation of international migration in states of the European Union and especially in the Czech republic. Although the international migration is very discussed theme, nobody till now has dealt with a total survey in the frame of the European community, which is also my contribution to given sphere of migration. The whole work is divided into five sections. The first two chapters are put near the theoretical aspects of migration and of the European union, which help better to make sense of given theme. The next section is focused on the analysis of the particular member states, which are consequently compared pursuant to chosen criteria and also is assessed the influence of these factors on migration by itself. In the last but one part the problems of migration in the Czech republic from different view-points is put near. The last chapter puts mind to the analysis of time series of net migration rate of the Czech republic whose result is construction of prognoses to the five years starting from year 2007.
