U.S. citizens are banned from visiting North Korea for the sixth consecutive year, the State Department announced Tuesday, extending travel restrictions due to the “serious risk” of arrest and long-term detention.

The ban prohibits U.S. passport holders from traveling “to, in and through” North Korea until Aug. 21, 2023, according to a notice posted by the federal government. But the restrictions also allow for exemptions for journalists, humanitarian workers and others who travel “in the national interest.”
