The United States and Korea agreed to reciprocity for their expedited customs and entry programs for "trusted" travelers.

The deal links the U.S. Global Entry program and Korea's Smart Entry Service. "Korea is the third country to have a fully reciprocal, publicly available trusted traveler program with the United States, joining the Netherlands and Canada, and is the first permanent trusted traveler program the United States has in Asia," according to a DHS statement. Germany, Israel, Mexico and the United Kingdom also have worked with the United States on such expedited entry programs.
