Why does the U.S. travel ban on refugees need to be revised?

Travelers traveling to and from the United States will be required to present their government-issued travel documents and must be vetted by the federal government.

But those who are from countries with histories of terrorism or those deemed a security risk, like Iraq, Syria and Iran, will still be exempt from the ban.

There are currently 6 million refugees and immigrants living in the United Sates, with nearly half of those in the U .

S. born in another country.

The ban was lifted on March 6, 2017.

The White House has said the ban will not impact the refugee population, and it does not include refugees from Iran, Iraq, Somalia or Sudan.
