This chapter explains different definitions of citizenship including citizenship as status, as rights, as participation, and as identity. It highlights key immigration laws and periods of immigrant inclusion and exclusion. The chapter also presents basic data on demographic change through American political history.

One of LBJ’s signature civil rights achievements, the 1965 Hart–Celler Immigration Act still stands in providing the overarching structure for immigration regulation in the US today. Its enactment ended decades of overtly racist immigration laws, crowning the almost equally long campaigns by immigration reformers seeking a more egalitarian system. In securing passage of the legislation, LBJ provided essential leadership but accepted significant compromises to do so. The immigration overhaul succeeded in abolishing the most discriminatory aspects of the old system for immigration regulation, even as it has implemented new forms of inequalities that have criminalized migrations particularly from the US’s closest neighbors. This law has transformed the US through the most diverse immigration in national history, even as it has produced a large and persistent caste of second-class residents whose unauthorized immigration bars them from citizenship.

In the first half of the twentieth century, Latin America was a region of immigration, where people moved from one country to another and/or people came from other continents, mostly from Europe. But by the 1960s, when many Latin American countries were suffering economic downturns, and the 1970s and 1980s, when state repression intensified, immigration turned to emigration, and many began making their way to the United States. Today, Latin Americans continue to migrate to the United States; people from all over the globe migrate to Latin America; and people move within the region. It is one of the most complex challenges confronting the United States and Latin America, and remains a very divisive issue in most countries of the region, especially the United States. This chapter looks at the push and pull factors that lead people to move from their home countries to resettle elsewhere.
