Here are a few of the stories that have emerged from American airports across the country.
Philadelphia International Airport
Two Syrian families who landed at Philadelphia International Airport Saturday morning were put on a flight back home.
The Assalis' six family members are on their way back to a war-torn Syria. This after President Donald Trump's executive order on immigration and refugees from six majority-Muslim countries.
The Assali family says they were counting down the days to see their extended family members. Four adults and two children boarded a plane for an 18-hour flight out of Syria. They were set to land early this morning. Upon landing at Philadelphia International Airport, they were detained. Hours later, they were put on a flight back home.
Sarmad Assali says each have Visas that were approved after a long, costly and legal process.
"We have gone through all the proper channels, paid all of these fees. They were supposed to arrive this morning at 7:45. At 8:30, we got a call from the airport authorities saying do not bother to come and pick up your family we are sending them back," said Sarmad Assali.
