Firstly, immigration can promote economic development. Immigration can fill the shortage of labor market and provide new skills and experiences for the country. Immigration can also create business opportunities, drive consumption, and increase tax revenue. Additionally, the cultural diversity brought by immigrants can promote international understanding and cultural exchange, and help cultivate global thinking.

At the same time, immigration may also bring crime and security threats, which may lead to political instability and social unrest.
