The international border states are those states in the U.S. that border either Canada, Mexico, Cuba, or Russia. With a total of eighteen of such states, thirteen lie on the U.S.–Canada border, four on the U.S.–Mexico border, and one consists of a maritime borders with Cuba and The Bahamas.

States along U.S.–Canada[edit]

Thirteen states lie on the U.S.–Canada border. The U.S. states of Indiana, Illinois, and Wisconsin do not share a direct geographic border with Canada. They do, however, possess customs facilities due to their place along the Great Lakes, which leads to the Canadian border. (All three states connect Lake Michigan, while Wisconsin also connects to Lake Superior).
