RT Article T1 Ethical Theories and Approaches to Immigration in the United States: A Focus on Undocumented Immigrants JF Transformation VO 38 IS 2 SP 138 OP 157 A1 Sackey-Ansah, Alex LA English PB Sage YR 2021 UL https://ixtheo.de/Record/1763009661 AB The United States has dealt with issues on immigration for over a century. The largest wave of immigration before the late 20th century began in the 1870s and peaked in 1910 (Foley & Hoge, 2007). In the past few decades, the United States has dealt overwhelmingly with the issue of undocumented immigrants. This challenge has led to different approaches to immigration reform and to help regulate the influx of immigrants across its borders. Generally, however, there have been two major sets of voices indicative of the opinion of the American populace. One group has called for tighter immigration rules to prevent the easy entry of undocumented immigrants who have been branded as criminals. The other group has taken a moral and ethical stance to permit the entry of immigrants and to formulate a process for their legal residency. These two opposing views have triggered an ongoing discussion on undocumented immigrants.
