The article compares the main research agendas and methodological and theoretical approaches informing current studies of immigration and ethnicity in the United States and Europe (represented by six countries: the United Kingdom, France, Germany, Belgium, the Netherlands, and Sweden). The European part of the report focuses on the common features of immigration and ethnic research in the countries selected for examination as compared with the American studies. In accounting for the reported similarities and differences between the two continents, I identify the contributing circumstances in the examined societies at large as well as in the characteristics of the scholarly environment in which the research in question is conducted.
