Miami International Airport appeared to be business as usual on the first day of the Trump administration travel restrictions for nationals of Cuba, Venezuela and Haiti - countries that are a large source of travel and migration to South Florida.

President Donald Trump has banned travel to the U.S. by citizens of 12 countries and restricted access for those from seven others, citing national security concerns in resurrecting and expanding a hallmark policy from his first term that will mostly affect people from Africa and the Middle East.
