Trump Travel Order Bans People From 12 Countries From Entering U.S.

President Trump on Wednesday signed a travel ban on 12 countries, primarily in Africa and the Middle East, resurrecting an effort from his first term to prevent large numbers of immigrants and visitors from entering the United States.

The ban, which goes into effect on Monday, bars travel to the United States by citizens of Afghanistan, Myanmar, Chad, the Republic of Congo, Equatorial Guinea, Eritrea, Haiti, Iran, Libya, Somalia, Sudan and Yemen.

Mr. Trump also imposed restrictions — but stopped short of a full ban — on travel from Burundi, Cuba, Laos, Sierra Leone, Togo, Turkmenistan and Venezuela. People from those countries cannot come to the United States permanently or get tourist or student visas.

The travel ban is the latest move in Mr. Trump’s sweeping crackdown on immigration, including blocking asylum at the southern border and barring international students from Harvard University. His administration has also conducted immigration raids across the country.

The decision came just days after an Egyptian man in Colorado was arrested and charged with carrying out an attack on a group honoring hostages being held in Gaza. Trump administration officials had warned that there would be a crackdown after that attack.

“The recent terror attack in Boulder, Colo., has underscored the extreme dangers posed to our country by the entry of foreign nationals who are not properly vetted, as well as those who come here as temporary visitors and overstay their visas,” Mr. Trump said in a video message announcing the travel ban. “We don’t want them.”
