The objects of social work are diverse.

Globalization makes the objects of social work more diversified.

From the middle of18th century to the end of19th century, social work has developed from simple poverty alleviation to major professional fields. It has always been committed to helping individuals, families, communities and groups that have been damaged in society; Its task is to take all appropriate measures to help those who are in trouble because of poverty, disease and conflict, as well as because of the imbalance of individuals, families or social groups in the economic and social environment. If we say that at the beginning of globalization, different nationalities and countries were still in a relatively closed state, although a considerable number of immigrants from countries with earlier social work development such as the United States and Western Europe were once the aid targets of social workers, on the whole, the targets of social work are still mainly confined to nation countries. However, with the acceleration of globalization, not only the existing problems in our country are increasingly "globalized", but also the objects of social work are more diversified.

The first is the emergence of a large number of international immigrants. Many immigrants move between different countries every day in the world. The United States, which has always been regarded as an immigrant country, absorbs more than 1 10,000 immigrants from all over the world every year. The census in the United States shows that among the 28 1 10,000 people living in the United States, 3 1 10,000 people were born abroad, accounting for 1 1% of the total population, but the number of immigrants without legal documents has not been officially counted. These immigrants and illegal immigrants are mainly engaged in low-skilled jobs in the United States that do not require much education, such as chicken processing plants, meat packaging, light industrial manufacturing, agriculture, and hotels and restaurants. These immigrants "face many difficulties, and it is difficult for them to find stable jobs to support their families, let alone high-paying jobs." At the same time, the welfare reform of 1996 makes it difficult for people with financial difficulties, even legal immigrants, to obtain welfare benefits, medical security and even food stamps from the social security system. Immigrants who settle in these new places will be more or less under double pressure. On the one hand, many States are unwilling to provide help to immigrants; On the other hand, as the economy goes from bad to worse, immigrants in these States will lose their jobs at any time and cannot enjoy social welfare security. In order to help these immigrants from all over the world, social workers have carried out a series of work to help them adapt to the environment and improve their viability.

Secondly, with the acceleration of globalization, some events, disasters, conflicts and wars in the world have also made the clients of social work more diversified. In recent years, the number of refugees in Afghanistan, Iraq, Bosnia and other turbulent areas has been increasing. At the end of 1990s, about 40 million war refugees were displaced around the world. Among these refugees, 20 million are waiting for help in their own countries, and another 20 million are displaced to other countries. In Afghanistan alone, about one sixth of the population are refugees. The world we live in now is experiencing the phenomenon of mass evacuation and population alienation. Many social weak people are actually victims of racism and violence, such as sectarian conflicts in Iraq and Arab-Arab conflicts in the Middle East. Therefore, social workers must face the current situation of diversified recipients, and have the responsibility and ability to care for and help those who are psychologically hurt and deprived of their interests in violence, conflict and discrimination on a global scale.
