Foreign-born members of Congress have served in every session since 1789, because the Constitution lets naturalized citizens sit in either chamber once they meet a citizenship duration requirement — seven years for the House, nine for the Senate. In the current 119th Congress (2025–2027), 32 lawmakers were born outside the United States: 26 in the House and six in the Senate, or about 6% of the full body.1Congressional Research Service. Membership of the 119th Congress: A Profile Their birthplaces span 17 countries across four continents.
Who Can Serve
The natural-born citizen requirement people sometimes assume applies to Congress does not. It applies only to the presidency, under Article II, Section 1, which is generally read to mean someone who held U.S. citizenship at birth without needing to naturalize.2Constitution Annotated. Article II, Section 1, Clause 5 — Presidential Eligibility A naturalized citizen can rise to Speaker of the House or Senate majority leader but cannot serve as president.
For the House, Article I, Section 2 sets three requirements: a representative must be at least 25 years old, must have been a U.S. citizen for at least seven years, and must live in the state they represent at the time of election.3Constitution Annotated. Article I, Section 2, Clause 2 — Qualifications of Members For the Senate, Article I, Section 3 raises the minimum age to 30 and lengthens the citizenship requirement to nine years.4U.S. Senate. Senators Born Outside the United States
The Supreme Court has confirmed that these are the only qualifications. In Powell v. McCormack (1969) and U.S. Term Limits, Inc. v. Thornton (1995), the Court held that neither Congress nor the states can add to them.3Constitution Annotated. Article I, Section 2, Clause 2 — Qualifications of Members A state cannot, for example, require a longer period of citizenship for its own delegation.
Who Serves in the 119th Congress
The Congressional Research Service counts 26 foreign-born representatives and six senators in the 119th Congress, and notes that some of them were born abroad to American parents working or serving overseas rather than as foreign nationals.1Congressional Research Service. Membership of the 119th Congress: A Profile
The House
The 26 foreign-born House members come from 17 countries. Mexico is the most common birthplace with four members: Salud Carbajal (D-CA), Juan Ciscomani (R-AZ), Jesús “Chuy” García (D-IL), and Raul Ruiz (D-CA). Three each were born in Germany (Becca Balint, Sharice Davids, David Rouzer) and India (Pramila Jayapal, Raja Krishnamoorthi, Shri Thanedar). Two each were born in Peru (Robert Garcia, James Himes), South Korea (Young Kim, Marilyn Strickland), and Ukraine (Victoria Spartz, Eugene Vindman).5U.S. House of Representatives, Office of the Clerk.

The Senate
Six sitting senators were born outside the United States: Michael Bennet of Colorado (born in India), Ted Cruz of Texas (born in Canada), Tammy Duckworth of Illinois (born in Thailand), Mazie Hirono of Hawaii (born in Japan), Bernie Moreno of Ohio (born in Colombia), and Chris Van Hollen of Maryland (born in Pakistan). Bennet, Cruz, Duckworth, and Van Hollen were born to American parents abroad, a distinction the Senate’s own records flag with an asterisk.4U.S. Senate. Senators Born Outside the United States
How the Citizenship Rules Have Been Tested
The duration requirements are not decorative. The most significant early challenge involved Albert Gallatin, a Swiss-born senator elected from Pennsylvania in 1793 and then denied his seat because he had not been a U.S. citizen for the required nine years.6Constitution Annotated. Article I, Section 3, Clause 3 — Senate Qualifications He served in the House instead and later became one of the longest-serving Treasury Secretaries in American history.
James Shields, an Irish-born senator elected from Illinois, was likewise denied his seat for coming up short on the citizenship clock. He won the special election that followed, once he had cleared the nine-year threshold, and went on to serve as senator from three different states (Illinois, Minnesota, and Missouri), the only person in American history to do so.6Constitution Annotated.

The Longer Arc
Foreign-born representation in Congress has shifted dramatically over more than two centuries. Roughly 10% of members of the first Congress (1789–1791) were born abroad — nine out of 95. The share peaked at about 8% during the 50th Congress (1887–1889), when 31 of 407 members were foreign-born, alongside the major European immigration wave of that era.7Pew Research Center. Fewer Immigrants in Congress Today Than in Years Past
Then it collapsed. Between 1967 and 1974, no foreign-born member served in either chamber. As recently as the 114th Congress (2015), only six did, about 1% of the body. Across the entire history of Congress, 407 foreign-born Americans have served among more than 12,000 total members.7Pew Research Center. Fewer Immigrants in Congress Today Than in Years Past
The current 6% share is the highest in decades but still trails the foreign-born share of the U.S. population, which stood at 13.6% as of 2021.8Pew Research Center. The Changing Face of Congress On the Senate side alone, the chamber’s records list 74 senators born outside the United States across its entire history, most commonly in Ireland (17), Canada (14), and England (12).4U.S. Senate.

How Members Got Here
The personal routes to Congress vary as much as the countries of birth.
