Sounds like a big economic impact right?
"The National Travel and Tourism Office today announced that international visitors spent more than $21.2 billion on travel to, and tourism-related activities within, the United States in December, an increase of nearly three percent ($564 million) when compared to December 2015 - setting a new record for monthly U.S. travel and tourism exports.
International visitors spent a record-setting $247.1 billion on U.S. travel and tourism-related goods and services in 2016, an ever-so-slight increase (0.4%) when compared to record levels of spending in 2015; conversely, Americans have spent an estimated $158.9 billion abroad, yielding a balance of trade surplus of more than $88.2 billion for the year."
