United States senators born outside the United States. It includes senators born in foreign countries (whether to American or foreign parents). The list also includes senators born in territories outside the United States that were later incorporated into the United States (except for those born in the British colonies and territories in North America (or in the temporarily independent former British colonies and territories in North America) that would go on to form the United States of America).
^Gallatin won election to the
Senate in 1793, and took the
oath of office, but on the same day a petition was filed by nineteen Pennsylvania Federalists protesting that Gallatin did not have the minimum nine years of citizenship required to be a senator. After two months of deliberation, the matter went before a Senate vote where Gallatin was removed from the Senate with a party-line vote of 14–12.
