In the United States, a “Green Card” certifies that a noncitizen or “alien” is legally authorized to live and work in the country. Over the years, the coveted document has gone by many names, including “Alien Registration Receipt Card” and “Permanent Resident Card,” but most people still refer to it by the green paper first used to print the cards in the 1940s.
What was the Alien Registration Act of 1940?
In 1940, for the first time in U.S. history, the Alien Registration Act required all noncitizens and foreign nationals (14 or older) to register with the government. The law, signed by Franklin D. Roosevelt, was a World War II-era national security measure to identify and fingerprint millions of noncitizens already living in the country.
In a public statement, FDR sold the new registration requirement as a positive measure “not only for the protection of the country but also for the protection of the loyal aliens who are its guests.” Around 5 million aliens registered, encouraged by radio PSAs and newspaper photos of foreign-born actors and musicians happily complying with the new law.
The Alien Registration Act of 1940 didn’t target noncitizens from specific countries. In 1942, following America’s entry into World War II, FDR issued an executive order requiring the additional registration of all “alien enemies”—natives of Germany, Japan and Italy. That order paved the way for the forced removal and internment of Japanese Americans.
