In a world where the political climate is constantly in flux, immigration is a constant. Because of this, understanding the impact of immigration is crucial. This study will focus on the immigration-crime nexus and how national origin affects sentencing outcomes for all non-citizens in the United States. Using Racial Threat Theory and Integrated Threat Theory, I assume to find that certain national origins like Mexico, Africa, and the Middle East will have longer sentences than their European, Canadian and other regional counterparts. My research questions are as follows: Are there differences in sentencing based on an immigrant’s ethnicity? Does the national origin of the immigrant affect sentencing outcomes? I used United States Sentencing Commission Data from 2010-2012 to analyze my data. I ran multivariate regressions to analyze the effects of national origin on sentencing impacts for non-citizens during this time frame.
