Migration is a complex global problem that affects all countries, either as countries of origin, transit or destination, and thus create a different ethnic structure and relation between different cultures. Modern trends of global migration show increasing numbers of women immigrate what indicates the need for a systematic study of the gender aspect of migration movements and the establishment of gender-sensitive asylum system policies. The models and types of migration are primarily affected by push and pull factors. These factors are especially important in forced and mass migrations that are associated with global diaspora as examples of collective identity and the preservation of specific ethnic culture. Integration involves the participation of migrants in the basic structural aspects of the receiving country and their identification with the society. However, different models of integration confront many issues that directly or indirectly lead to ethnic conflict, disagreement and separation in the society. Importance of the human rights and respect of individual cultural identity in resolving the misunderstandings and encouraging different cultures coexistence is immense. The organizations such as Red Cross are established for raising awareness of migrant issues. They stand against all kinds of discrimination, prejudice and intolerance towards members of different cultural societies and help migrants in their psychosocial adjustment to the new environment. The legislative example of the successful integration is the law called Action Plan of the Migration Policy of the Republic of Croatia, which shows that Croatia is on the right path to become the multicultural country and that the foundation of a modern state is the acceptance of diversity and development of non-stereotyped views as well as non-judgemental attitudes.
