All U.S. passports are invalid for travel to, in, or through the DPRK unless specially validated for such travel under the authority of the Secretary of State.
Special validations are granted only in very limited circumstances. More information on how to apply for the special validation is available here.
Can I travel to North Korea?
While OFAC sanctions do not prohibit U.S. persons from traveling to or from North Korea, as of September 1, 2017, U.S. passports are invalid for travel into, in, or through North Korea. However, in limited circumstances, applicants may be eligible for a Special Validation Passport from the State Department that will allow them to travel for specific purposes. See travel.state.gov for additional details. U.S. persons who intend to travel to North Korea via a Special Validation Passport do not require OFAC authorization to engage in activities that are exempt pursuant to 50 U.S.C. § 1702(b), such as travel to or from any country or the importation or exportation of informational materials. All other activities outside the scope of this exemption would require a specific license from OFAC, unless otherwise authorized by OFAC. See, for example, FAQ 558 for additional information regarding news reporting organizations and journalists.
