The Trump administration signed a declaration on Wednesday that suspended travel to citizens of 12 U.S. countries: Afghanistan, Myanmar, Chad, Congo, Congo, Equatorial Guinea, Eritrea, Haiti, Iran, Libya, Somalia, Sudan, Sudan, Sudan and Yemen.

Announcement citing national security interests, noting that identified countries lack adequate review and screening procedures to detect foreign nationals who may pose a security or terrorism threat to the United States

The declaration also partially restricts the nationals of seven other countries: Burundi, Cuba, Laos, Sierra Leone, Togo, Turkmenistan and Venezuela.

Other considerations, it said, include a country's information sharing policy, the presence of terrorists, visa durability and whether it is easy to accept return citizens.

The ban is scheduled to take effect at 12:01 a.m. ET on Monday.

In a video released by the White House on Wednesday night, Trump said on his first day of office, he directed the Secretary of State to conduct a security review of "high-risk areas" to make travel restrictions.

He also cites Sunday's attack on Jewish protesters in Boulder, Colorado. Mohamed Sabry Soliman, the person accused of attack, was an Egyptian national. Egypt has not been named in the new travel ban.

The policy reflects a similar travel ban announced in January 2017, a week in Trump’s first term that banned travel from seven Muslim majority countries. The policy, while largely criticized, was eventually retained by the Supreme Court in 2018.

The ban was later ended in 2021 by President Joe Biden.

Democratic lawmakers visited social media to express opposition to the latest ban. These include D-Calif's Senators Adam Schiff and D-Mass. Senator Ed Markey, who posted on X: "Nice: Trump's latest travel ban won't make the United States safer. We can't continue to allow the Trump administration to write about paranoia and hatred about U.S. immigration policy."

The new policy applies to foreigners who are from outside the United States who lack visas entering as of Monday, June 9.

In addition to this rule, some travelers include permanent residents of the United States, athletes participating in major sports events, and direct family members, with “clear evidence of identity and family relationships” and take DNA as an example.
