The ban that Trump announced Wednesday takes effect at 12:01 a.m. Monday, a cushion that may avoid the chaos that unfolded at airports nationwide when a similar measure took effect with virtually no notice in 2017. Trump, who signalled plans for a new ban upon taking office again in January, appears to be on firmer ground this time after the Supreme Court sided with him.

Some of the 12 countries also appeared on the list of banned countries in the Republican president’s first term. The new ban targets Afghanistan, Myanmar, Chad, the Republic of Congo, Equatorial Guinea, Eritrea, Haiti, Iran, Libya, Somalia, Sudan and Yemen.

There will also be heightened restrictions on visitors from seven other countries: Burundi, Cuba, Laos, Sierra Leone, Togo, Turkmenistan and Venezuela. North Korea and Syria, which were on the banned list in the first Trump administration, were spared this time.

While many of the listed countries send few people to the United States, Haiti, Cuba and Venezuela had been major sources of immigration in recent years. Trump tied the new ban to Sunday’s terror attack in Boulder, Colorado, saying it underscored the dangers posed by some visitors who overstay visas. The suspect, who is accused of turning a makeshift flamethrower on a group of people, is from Egypt, which is not on Trump’s restricted list. The Department of Homeland Security says he overstayed a tourist visa. The travel ban results from a Jan. 20 executive order Trump issued requiring government agencies to compile a report on “hostile attitudes” toward the U.S. and whether entry from certain countries represented a national security risk.
