Throughout our nation’s history, foreign-born men and women have come to the United States, taken the Oath of Allegiance, and contributed greatly to their new communities and country. The United States welcomes individuals from na­tions near and far and immigrants have played an important role in establishing this country as the “land of opportunity.” America takes great pride in being known as a “nation of immigrants.”

The following section provides examples of individuals who have come to the United States, become citizens by choice, and left a lasting impression on our society. This list is by no means all encompassing, as a compre­hensive record would be nearly impossible. Instead, it serves the purpose of highlighting a selection of foreign-born Americans, com­ing from a wide range of coun­tries, who have had a significant impact on the United States as we know it today.

John Paul JonesJohn Paul Jones (1747–1792)

American naval officer. John Paul was born July 6, 1747, in Kirkbean, Kirkcudbrightshire, Scotland (now Dumfries and Galloway, Scotland).

In the mid 1770s, he moved to the British colonies in North America, adopting the last name “Jones.” At the be­ginning of the American Revolution, he joined the Continental navy and was commissioned first lieutenant. During the war, Jones commanded several vessels, including the Duc de Duras, which he renamed Bon Homme Richard in honor of Benjamin Franklin’s Poor Richard’s Almanack. Aboard this ship on September 23, 1779, Jones engaged the British vessel HMS Serapis off the coast of England.
