The Trump trauma, his anti-immigrant discourse, aggressivity and legislative damage are still present despite Biden's positioning as a "migration president." This book is meant to be a reflection on U.S. presidentialism regarding migration issues. The authors analyze President Joe Biden's first actions on immigration, in a dual exercise of comparison with his predecessor, Donald Trump, and a prospective analysis of what his chances are to be able to improve current immigration policy and further reinstate the U.S. as a moral power. The objective of this book is to culturally translate the U.S. tradition of analyzing the president's first hundred days in power into a more regional and long-term reading of what Biden has achieved, even though it is not always visible, for migrants in general and specifically for Latin Americans.
