The American tourism industry stands to suffer an $18 billion hit during the next two years amid President Donald Trump’s continuous travel-ban push.

A federal judge in Hawaii indefinitely extended on Wednesday an order blocking enforcement of Trump’s revised ban on travel to the United States from six predominantly Muslim countries, Reuters reported.

Foreign tourism is a $250 billion-a-year business in the United States, and Trump’s original and revised executive orders temporarily banning travel from majority Muslim countries — put on hold by federal courts — have dampened interest worldwide in visiting the U.S., USA Today quoted travel and tourism executives as saying.

“The U.S. has put an unwelcome mat at our front door,” said Henry Harteveldt, president of Atmosphere Research Group, which conducts travel research.

Airline bookings fell after the Jan. 27 and March 6 travel ban announcements, and hotels reported lighter occupancy in February, USA Today said.
