The proclamation, which Trump administration officials say carries the weight of an executive order, spells out different restrictions for different countries, ranging from total bans for North Korea, Syria, Libya, Yemen, and Chad to just a ban on Venezuelan government officials and their families.
President Trump is expected to announce new country specific restrictions on travel, which will replace the current restrictions on travelers from six Muslim-majority nations.
And the inclusion of North Korea and Venezuela appears to be mostly symbolic.
During the presidential campaign, Trump explicitly called for a ban on Muslims entering the country.
The American Civil Liberties Union said, " the addition of North Korea and Venezuela doesn't obfuscate the real fact that the administration's order is still a Muslim ban". "The fact that Trump has added North Korea - with few visitors to the USA - and a few government officials from Venezuela doesn't obfuscate the real fact that the administration's order is still a Muslim ban", said Anthony D. Romero, the executive director of the American Civil Liberties Union.
There are some exceptions for nationals from the eight countries who have "bona fide" connections to the US, though narrower than what was ordered by the Supreme Court in its temporary ruling on the travel ban. "We're talking about countries that were willfully non-compliant and refused to engage with the United States".
The travel restrictions vary based on the country.
A blanket ban on all refugee entry into the USA, except for those with close family already in the country.
"The tougher, the better", Trump said about the ban Sunday. The coalition called the ban, which also suspends for 90 days refugee entries, "nothing more than religious intolerance masquerading as an attempt to address (unfounded) security concerns".
The new restrictions, according to senior administration officials, were a result of a worldwide review based on a new baseline for information sharing and for vetting procedures for those seeking entry into the U.S.
"We will not admit those into our country we can not safely vet", Trump tweeted late Sunday after the new policy was announced.
"It is senseless and cruel to ban whole nationalities of people who are often fleeing the very same violence that the US government wishes to keep out".
"The travel ban into the United States should be far larger, tougher and more specific", Trump tweeted September 15, hours after a homemade bomb on a city subway injured dozens.
For instance, foreign nationals from North Korea are banned, but a student from Iran will be allowed in, subject to "enhanced screening and vetting requirements".
"As president, I must act to protect the safety and interests of the United States and their people", said Donald Trump in this decree made public on Sunday evening. The order also permits, but does not guarantee, case-by-case waivers for citizens of the affected countries.
The U.S. Supreme Court is scheduled to hear oral arguments October 10 on the constitutionality of the March travel ban.
