Citizenship Status of Immigrants
How many foreign-born residents in America have U.S. citizenship?
Naturalization is the process of gaining citizenship after birth. The remainder of foreign-born residents are non-citizens. The American Community Survey does not break down the non-citizen foreign-born population by status.
Non-citizens may be lawful permanent residents—holders of a so-called "green card." They may also be conditional permanent residents, refugees and asylum seekers, or people visiting the United States on non-immigrant temporary visas, such as students. According to estimates from both the U.S. Department of Homeland Security and the Migration Policy Institute, more than 11 million immigrants in the United States are unauthorized, also known as undocumented or illegal aliens.
