Border Crossings Between United States and Russia

Separated by the narrow waters of the Bering Strait, Russia and the United States share a border that is closer than many expect. At its narrowest point, the two countries are just under 4 kilometers apart between the Diomede Islands. Despite this proximity, there are **no official border crossings** for travelers. Movement between the two nations requires flights or sea routes via other countries, as this maritime boundary has no functioning checkpoints.
