Immigration enforcement involves the policies and actions implemented by governments to regulate and control the flow of immigrants into a country. This includes border control measures, visa restrictions, deportation of unauthorized immigrants, and other enforcement mechanisms to ensure compliance with immigration laws. Immigration enforcement is a contentious and complex issue, with debates surrounding the ethical considerations, human rights implications, and economic impacts of enforcement practices. Researchers in this area study the effectiveness of various enforcement strategies, the legal frameworks governing immigration enforcement, and the social and political consequences of enforcement actions.
