The diploma thesis deals with the issue of immigration and its impact on the economy in Australia, Great Britain and the United States of America. In the introduction, various migration theories explaining the migration motifs and immigration policies, whose specifics and the type of requirements of the monitored countries sheds the composition of incoming individuals, are discussed. This profile is complemented by the analysis itself, which examines the socio-economic factors of foreign-born population living in the monitored countries. This analysis is carried out by cross-sectional data comparisons, but it monitors the arrival times of individuals, providing an overview within the timeline. In order to determine the impact of immigration on employment and average wages, regression was used, but this effect was in no way proven beyond the impact on average wages in Australia.

The themes of migration and integration are presently quite controversial in the public, academic, and political spheres. Therefore, a lack of solid, tried-and-true, and easily accessible science investigation is to blame for numerous preconceptions that are frequently associated with migration and for the poor integration of the migrant community. In order to give judgement a stronger information foundation and to encourage a more educated general populace, the Systematic Literature Review (SLR) of immigration and their relative characteristics in Nordic countries is essential in establishing fundamental research and adequately funding creative methodological methods and initiatives. This research aimed to determine the difficulties of the Nordic nations' labour markets that experience as a result of immigration based on SLR. It mainly focuses on the main issues or challenges faced by immigrants in Nordic countries. Qualitative research examines the difficulties of immigration in a Nordic country. The foremost goal of the investigation is to identify the outcomes of subsequent research query such as 1.What are the Challenges faced by the Nordic labour sector due to immigration? 2. Why Nordic labor sector face challenges due to immigration? The theoretical framework is established in this review to highlight the immigrant’s work-life balance and immigration impacts on Nordic countries. Moreover, the data collected from different database for qualitative assessment. The qualitative results analysis was compared to the theoretical framework to identify the deviation and alignments in current SLR. The study found the various challenges faced by Nordic citizens in labour sector due to immigration.Future research will expand on prospective research to examine how factors in the immigrant's demographics, contextual labour market characteristics, and the language used in the destination society affect the interactions between labour market integration.
