1. Introduction Europe has had experience and a long history of migration, both immigration and emigration. Migration to contemporary Europe is a part of phenomenon of international migration inherent in the process of globalization. During the last couple of decades migration, and particularly immigration (and the immigrant population) has become an increasingly significant issue in European societies. The process of migration and presence of immigrants is shaping much of the nature and content of social, economic and political dynamics in contemporary Europe. In rapidly altering milieu, from facing issues related to integration of immigrants and minorities to religious fundamentalism, uncertainties and economic slowdown Europe is confronting challenges like never before in past fifty years. Among these, the integration of the 'others', the immigrants, is a major challenge. The process of integration and differentiation of immigrant communities is happening simultaneously in social, cultural, economic and political sphere. A number of policies have been adopted to address the issue. This paper is divided into four sections. The first section attempts to define who the 'others' in Europe are and why there is a cultural conflict. The second section deals with policy options for promoting social integration and their relative strengths. The third section deals with issues and challenges in social integration of 'others', and the last section analyses inter-culture as an effective way to promote social integration and dwell into why Europe needs to integrate the 'others'. Migration and the presence of immigrants is one of the hotly debated issues across Europe. The patterns of migration, the size and composition of migrant populations, to and from Europe have changed greatly over time, reflecting both current and historical patterns of migration flows (i) According to Jean-Pierre Garson and Anais Loizillon, (2003) throughout the second half of the 20th century, European countries have experienced four main migration periods. These are (ii) a) Employment-related migration and the reconstruction of Europe, b) Economic crisis and new migration adjustments: increasing flows of family reunification and the permanent nature of migration, c) diversification of host and sending countries and the increase in the flows of asylum seekers, refugees and ethnic minorities, d) The return of employment-related migration with a preference for skilled workers and temporary migration. Along with this the disintegration of the Soviet Union led to rapid economic and political transition of former communist countries of Central and Eastern Europe. Amidst this transition/ turmoil a large number of people migrated to west Europe in search for better prospects, stability and security. Although these patterns are indicative of specific trends and flows of people but what is more significant is that this process has altered the socio-cultural and demographic composition of Europe to large extent. These movements led to emergence of a distinct demographic mosaic combining pieces of diverse socio, cultural, linguistic, ethnic, religious and regional peculiarities. Cultural diversity has become a feature of almost all the European countries. If we look at the statistics explaining the demographic composition then in 2012, there were 34.3 million foreign citizens (iii) in the EU, representing 6.8 % of the total population. More than one third (17.2 million) of these people were citizens of another EU Member State. In most Member States, the majority of resident foreigners are third-country (iv) nationals. As per the statistics of the year 2012, in almost all the other Member States the majority of foreigners are non-EU citizens with only Luxembourg, Cyprus, Ireland and Belgium being an exception. The data shows that more than 75% of these foreigners in the EU resided in Germany, Spain, Italy, the United Kingdom and France. (v) As per the statistics in 2011 the United Kingdom (vi) reported the largest number of immigrants and along with Germany, Spain and Italy, these four Member States only together accounted for 60. …
