Dennis Rodman will be disappointed to learn that the US is set to ban all citizens from traveling to North Korea, according to two agencies that operate tours there. Koryo Tours and Young Pioneer Tours said the ban would be announced on 27 July to come into effect 30 days later, the BBC reported. “After the 30-day grace period any US national that travels to North Korea will have their passport invalidated by their government.” The ban comes one month after US student Otto Warmbier died following his imprisonment by the Kim regime.
