The Nepalese government recently denied visas to two North Korean restaurant workers after they attempted to leave and re-enter the country to renew their documents, local media reported on Tuesday.

According to the Annapurna Express, the two workers had attempted to refresh their tourist visas by traveling to China and then returning to Nepal, but were denied entry by the country’s immigration authorities.

“We found out that they had gone to China for a night, hoping that their visas would be renewed when they came back to Nepal,” an immigration official said in comments carried by the Annapurna Express
