The objective of this work is to analyze the most relevant contributions in the field of study of migrant caravans. To achieve this objective, first by way of contextualization, a historical review of the different migrant caravans is made. Second, four key discussions are analyzed to understand this phenomenon: 1) the caravans as a form of mobility, 2) as a social movement, 3) the politicization of these marches by government actors and 4) the media visibility of the caravans and their presence on social media. Likewise, it is highlighted how each of these axes can be strengthened through the analysis of the new migrant caravans and through the comparison between the various marches. [ABSTRACT FROM AUTHOR]

The Andrés Manuel López Obrador administration has had to manage migration in transit through Mexican territory - including migrant caravans - facing the demands of the Donald Trump government that Mexico prevent migrants from reaching US territory. The objective of this work is to analyze the changes and continuities in immigration policy during the first year of López Obrador through a documentary review and analysis of the data from administrative records. In addition, two key aspects of this policy are reviewed: the containment of migration and the protection of migrants. [ABSTRACT FROM AUTHOR]

The aim of this article is to analyze the restrictive and persecutory policies of the state of Arizona and Maricopa County between 2005 and 2013, as well as their effects on Mexican families residing in the state. The author argues that these policies have put into practice the attrition-through-enforcement strategy (ate). Based on document review and interviews carried out in Phoenix, Arizona, he analyzes three types of policies: 1) exclusion from benefits and public services; 2) restricted access to certain labor market niches; and 3) sanctioning, criminalizing, and promoting deportation.

Setting immigration policy is reserved for the federal government in both Mexico and the United States. However, de facto, the states in both countries carry out certain immigration policies. Chiapas and Arizona have both faced challenges in this area. The government of Arizona has followed an anti-immigrant logic, while the government of Chiapas has focused on the defense of migrants' human rights. The aim of this article is to understand the practically opposite roles played by these two states in managing immigration. [ABSTRACT FROM AUTHOR]
