Eleven United States presidents and three presidents-elect have made thirty-four presidential visits to Central America. The first visit by an incumbent president to a country in Central America was made in 1906 by Theodore Roosevelt. The trip, to Panama, was the first international presidential trip in U.S. history, and signaled the start of a new era in how presidents conducted diplomatic relations with other countries. In 1928, Herbert Hoover, during the time when he was president-elect, visited the region during his historic “good will” trip, to Central and South America.
