Mass migration is a serious challenge in both America and Europe. Hence the question of the ethical limits of hospitality. The answer must consider not only the needs of migrants, but also the ability of the host country to integrate migrants. This depends not only on the size of the migration, but also on its homogeneity. For example, a peculiarity of the current migration to Europe is the strong dominance of Muslims, which is changing its religious demographics and, consequently, European culture.
