Naturalizations
A rising number of people are becoming U.S. citizens, following the waves of immigrants coming to America over the centuries.
Annual number of new U.S. citizens
Naturalization, the process by which immigrants take citizenship in the United States, extends to foreign nationals the same rights and responsibilities as those held by the native-born. The final step is being sworn in as a U.S. citizen during an oath-taking ceremony. This chart shows how many immigrants have naturalized annually since the early 20th century, via civilian or military pathway.
According to the Migration Policy Institute, 969,380 people were naturalized in 2023. The overall immigrant count is about 47.8 million, representing 14.3% of the U.S. population
In 1991, 1.82 million permits for permanent residency, aka green cards, were issued, the most ever. The second-most, 1.28 million, were issued in 1907. Green card holders are permitted to live and work in the country indefinitely, to join the armed forces and to apply for U.S. citizenship after five years (three if married to a U.S. citizen).
