A stronger dollar course and a travel ban from six Muslim countries, could make tourism decline in the U.S according to travel industry representatives. And who gets the blame for this potential outcome? President of the United States Donald J. Trump.

Trump signed a revised executive order this week, banning citizens from six Muslim nations from travelling to the United States.

Those countries account for a tiny percentage of U.S. visitors, but there is growing concern that the order could hurt the image of the United States and scare other tourists away, Reuters reports.

According to a survey by the Global Business Travel Association (GBTA) indicated business travel, an important source of income for hotels and airlines, could suffer due to the ban.

37 percent of U.S. business travel professionals said they expect a reduction in their company's travel because of Trump's revised executive order, while 17 percent of European travel professionals said their company has already cancelled business travel to the United States, according to Reuters.

Another factor to take into account, is the U.S. dollar that has gained more than 5 percent against the euro over the past six months, making it more expensive for travellers to visit the United States.
