Individuals hold a wide range of beliefs and ideas on immigration throughout Western societies. Some are highly embracive of immigrants while others want draconian restrictions. This mixed-methods study conducted in the U.S. examines these beliefs, specifically on immigration being a human right. Particular attention is given to the rationales of those advocating for more open immigration policies and those opposed to them. The analysis reveals that individuals appeal to economic arguments both to advocate for and against greater immigration. Issues of security and order are also employed to argue against immigration; In contrast, participants use ethical themes and the history of the United States in arguing for immigration as a human right. Others highlighted normative restrictions across the world as a reason to reject the idea. The findings of this study can help inform both researchers and immigration advocates as they seek to understand the complex perceptions of immigration.
