Visitors to seven countries, including North Korea, are barred from entering the United States. They were banned from coming to the United States without a visa. You can come to the country using other visas instead. The ban is for those who have visited eight countries, including North Korea, Libya, Somalia, and Syria. Those who have visited these countries after March 1, 2011, will not be able to visit the United States without a visa. Instead, they can come to the US with tourist or business visas.
But 38 countries, including South Korea, Japan, and France, have announced that they will be without a visa for the next 90 days. The announcement was made on the website of the US Customs and Border Protection Department. The decision will be a blow to foreigners in the United States. Thousands of people are tourists in the country.
