As per details posted on the US Customs and Border Protection website, they will have to apply for tourist or business visas.<br />''<br />''The other seven countries – most of them in the Middle East – were already on the exclusion list.<br />''<br />''The change will affect thousands of people from visa waiver countries who have gone to the North as tourists or for other purposes in recent years. It will also put a damper on South Korean President Moon Jae-in's hopes of promoting cross-border tourism projects.<br />''<br />''US citizens have been banned from visiting North Korea since 2017 after an American student detained in Pyongyang was released in a coma and died a few days later.<br />
