Maurice Ferre becomes mayor of Miami, making him the first Puerto Rican to lead a major city in the mainland United States.

Congress passes the Equal Educational Opportunity Act to create equality in public schools by offering bilingual education to Hispanic students.


Russian-born immigrant Emmy Shafer spearheads a campaign to put an end to bilingualism and make English the official language of Miami. Her push for an English-only Miami is a harbinger of broader anti-immigrant sentiment that would spread across the country in the late 20th and early 21st century.


In the spring, Fidel Castro announces that any Cuban who wishes to leave may do so. Shortly after this declaration, a ramshackle armada sails from South Florida to the port of Mariel.

Twenty-five other Hispanics are appointed to positions needing Senate confirmation under this presidency.


NAFTA takes effect, eliminating all tariffs between Canada, Mexico, and the United States within 15 years. Imports from the maquiladoras become duty-free.

This bans undocumented immigrants from receiving public education and benefits such as welfare and subsidized health care (with the exception of emergency services); makes it a felony to manufacture, distribute, sell, or use false citizenship or residence documents; and requires any city, county, or state officials to report any suspected or apparent illegal aliens.


Proposition 187 is ruled unconstitutional, on the grounds that only the federal government has the authority to regulate immigration. Eliseo Medina spearheads the movement to file lawsuits against Proposition 187.

Medina becomes the first Mexican American Vice President of the Service Employees International Union.
