To deal with the growing migrant crisis in North Africa, several states have considered granting amnesty to foreign displaced persons (both economic migrants and potential refugees) who have entered their territories clandestinely. Morocco has taken the lead in this policy approach, launching two successful amnesty campaigns in 2014 and 2017 that regularized the status of approximately 40,000 displaced persons in total. While policymakers in many North African states increasingly see this policy as a viable solution, it is less understood how ordinary citizens view such regularization policies. Hence, this article inquires: under what conditions do ordinary native citizens support regularizing clandestine migrants and refugees? Further, what factors correlate with either higher or lower levels of public support for (or opposition to) regularization campaigns? Drawing on an original representative public opinion poll from Morocco's Casablanca-Settat region completed in 2017, this article finds that more than 59 percent of native citizens of Morocco support these regularization campaigns. Particularly, Moroccans who were wealthier, female, and ethnic minorities (black Moroccans) endorsed regularization more strongly. By contrast, Moroccans opposed regularization when they had concerns about whether displaced persons hurt the economy, undermine cultural traditions, and reduce stability.
