America is a nation of immigrants.
While immigration remains a topic of debate, it cannot be denied that the country we enjoy today, featuring world-class innovation, creativity and opportunity, would not be possible without the contribution of foreign-born persons who’ve chosen to live permanently in the United States.
Here are just a few foreign-born American citizens who’ve overcome the hardships that accompany relocating to a new country.
Former US Secretary of State Madeleine Albright: Czech Republic
Madeleine Korbel Albright was born Marie Jana Korbel on May 15, 1937, in Prague, Czechoslovakia, (now the Czech Republic). As a child, her family escaped Czechoslovakia 10 days after the Nazi invasion and fled to the United States.
When Albright became a US citizen in 1957, she changed her legal name to Madeleine.
After completing her degree at Wellesley College, and while working towards her Ph.D. at Columbia University, she began working for Maine Sen. Edmund Muskie as his chief legislative assistant. Albright continued to build her career in Washington, DC, working in foreign affairs and politics.

In 1993, she was confirmed as the US ambassador to the United Nations. Three years later ,Albright made history when she was appointed secretary of state by President Bill Clinton – the first woman to hold the position.
Under her leadership, the US State Department worked to spread democracy across the Middle East, expand NATO eastward to include some of the former Soviet nations and further the normalization of US relations with Vietnam.
Albright left the State Department at the end of the Clinton administration in January 2001 and has remained active in foreign affairs. In May 2012, she was awarded the Presidential Medal of Freedom by President Barack Obama.
Author and Presidential Medal of Freedom recipient Isabel Allende: Peru
Internationally renowned author Isabel Allende was born on August 2, 1942 in Lima, Peru, and spent most of her childhood living in Chile. She received her primary education in American and English private schools and began her career as a translator and journalist in her 20s.
Allende gained notoriety in Chile when she co-founded the first feminist magazine in the country, Paula. In 1981, she began writing a letter to her dying grandfather. Four years later the letter had evolved into her first novel, “The House of the Spirits,” launching her career as a novelist.
Her works cover a wide range of themes including social justice, feminism, politics and more. The author of more than 20 titles, Allende’s books have impacted the globe, translated into dozens of languages and selling more than 60 million copies.
In 2014, she was selected to receive the Presidential Medal of Freedom – the highest civilian honor in the United States.
Google co-founder Sergey Brin: Russia
The co-founder of Google, the most visited website in the world, was born on August 21, 1973 in Moscow, Russia. When he was 6 years old, his family emigrated to the United States.

Entertainer Bob Hope: England
Acclaimed comedian and well-known actor Leslie Townes Hope was born May 29, 1903, in Well Hall, England. At the age of 4, Hope, along with his parents and siblings, passed through Ellis Island near New York City, before settling in Cleveland, Ohio. As a young man from a modest upbringing, Hope worked as a butcher’s assistant and shoe salesman, and would perform and tell jokes in the park. His hard work and enthusiasm for performing would eventually land him on Broadway with his partner, George Byrne.
Hope’s career careened from the Broadway stage and into radios around the country. The exposure would eventually lead him to the big screen, where he would appear in films with stars such as Bing Crosby. Sticking to the comedy genre, Hope was familiar to everyone and was featured on virtually every media platform. He gained broader recognition when he began to take time off from his radio and film roles to entertain America’s troops during World War II. Throughout his career, the comedian would bring laughter and cheer to battlegrounds of five wars, headlining 57 events for servicemen and women. In 1997, the United States Congress recognized Hope’s work with service members by naming him an honorary veteran of the US military.
Hope hosted the Oscars 16 times (but never took home an award himself), entertained 11 US Presidents, authored 12 books and, despite never completing high school, he received 56 honorary doctorate degrees.
Hope died in 2003 in Los Angeles.

UNICEF global ambassador, NBA star Dikembe Mutombo: Democratic Republic of Congo
Born in the Democratic Republic of Congo, retired NBA star Dikembe Mutombo came to the United States in 1987 on an academic scholarship at Georgetown University to study medicine with intentions to return to help people back home.
But fate changed that plan – leading him to the school’s basketball team and eventually to the NBA – allowing Mutombo to follow a mission far beyond his wildest dreams.
Known as one of the greatest NBA players to never win a championship, the center forward won the league’s defensive player of the year award four times and played in eight All Star games.
During his 18 years in the league, Mutombo was known for his focus on international service and aid. In 1993, he traveled with then-NBA Commissioner David Stern and famed Georgetown colleagues Patrick Ewing and Alonzo Mourning to the South African cities of Cape Town and Johannesburg.
In 1997, two years before retiring from the NBA, Mutombo established the Dikembe Mutombo Foundation with a mission to improve the health, education and quality of life of people in the Democratic Republic of the Congo.
The foundation’s largest project was the construction of the Biamba Marie Mutombo hospital in the capital city of Kinshasa.
Mutombo contributed $15 million of his personal funds toward the project’s $29 million total. The building was named after his mother, who died of a stroke the same year he founded the organization.
In 2000, he received the President’s Volunteer Service Award, the United States’ highest honor for volunteerism.
In 2009, Mutombo was appointed the NBA’s first global ambassador. Today he continues his ambassador role and humanitarian work through his foundation, while working with other organizations to further his mission to help the poor around the world.
Architect Ieoh Ming Pei: China
World-renowned architect Ieoh Ming Pei was born in Guangzhou, China, on April 26, 1917. When he was 17, he moved from Shanghai to the United States to study at the University of Pennsylvania. Pei completed his undergraduate studies at the Massachusetts Institute of Technology in 1940. He earned his master’s degree in architecture from Harvard University in 1944, and later moved to New York City to start his career.
Pei’s first building was constructed in Atlanta, Georgia, a two-story office building that garnered praise in the industry. His status among architects rose with his design of the National Center for Atmospheric Research building in Colorado, completed in 1971. The success caught the attention of many, including Jacqueline Kennedy Onassis, who chose Pei to design John F. Kennedy’s presidential library.
Following the opening of the Kennedy library, Pei became one of the world’s most sought-after architects. He designed the Rock and Roll Hall of Fame in Cleveland, Ohio, a new entrance to Louvre museum in Paris, France, and Washington, DC’s United States Holocaust Memorial Museum, to name a few.
Now 101 years old, Pei has taken a less involved role in the work of his firm, but continues to remain a part of the projects around the world.
