Major New York City immigration advocacy groups have condemned a third iteration of President Donald Trump's January travel ban, announced Sunday in the form of a presidential proclamation. This latest version imposes full or partial travel restrictions or heightened screenings on nine countries, and is the first indefinite travel order. It is also the first to stray from majority-Muslim countries, impacting North Korea and Venezuela as well as Chad, Iran, Iraq, Libya, Syria, Somalia and Yemen.

It is set to go into effect on October 18th.

All immigrants from Chad, Libya and Yemen will be barred, as well as nonimmigrants on business and tourist visas from those countries. In the case of Iran, all immigrant and nonimmigrant travel is suspended with the exception of of certain student visa holders, who will be subject to "enhanced screening." All immigrants and nonimmigrants from North Korea and Syria will be barred without exception, as well as certain government officials from Venezuela and their families. In the case of Somalia, immigrants will be barred and visitors will be subject to additional screenings.

Iraqis, who were spared from the second iteration of the ban, will be subject to heightened screenings. Sudan, part of the original travel ban, is no longer on the restricted travel list.

"This is different from the original travel plan in some structural ways," said Camille Mackler, Director of Immigration Legal Policy at the New York Immigration Coalition, in a Monday press briefing. "It's a lot more detailed in its reasoning, and it also separates out how the different countries are going to operate."

"A lot of questions remain and the actual impact is a lot of people are going to be left in limbo nonetheless," she added.

The new guidelines are the result of a Homeland Security review of "nearly 200" countries that launched in March, according to yesterday's proclamation. The countries included in the new ban "remain deficient at this time with respect to their identity-management and information-sharing capabilities, protocols, and practices," it states. "In some cases, these countries also have a significant terrorist presence within their territory."

"My highest obligation is to ensure the safety and security of the American people, and in issuing this new travel order, I am fulfilling that sacred obligation," Trump stated Sunday.

The American Civil Liberties Union and major immigrant advocacy groups, including the New York Immigration Coalition and the Council on American-Islamic Relations, immediately dismissed the new guidelines as an attempt to slightly modify the original ban, which faced immediate legal challenges, in order to push it through. (Trumps travel restrictions were "never, ever, ever” based on race or religion, a White House Official told reporters over the weekend.)

"This is a dressed-up Muslim Ban, the sole purpose of which is to double down on the Trump Administration's systematic and unconstitutional anti-immigrant agenda," said NYIC Director Steven Choi in a statement.

"Six of President Trump's targeted countries are Muslim," added Anthony Romero, executive director of the American Civil Liberties Union. "The fact that Trump has added North Korea—with few visitors to the U.S.—and a few government officials from Venezuela doesn't obfuscate the real fact that the administration's order is still a Muslim ban. President Trump's original sin of targeting Muslims cannot be cured by throwing other countries onto his enemies list."

Nihad Awad, national director of CAIR, described the latest ban as a fresh example of Trump's white nationalism.

"With this latest iteration of the discriminatory and unconstitutional Muslim ban, coupled with the race-baiting of professional athletes exercising their First Amendment rights and a reluctance to condemn neo-Nazis in Charlottesville, President Trump once again demonstrates that his views and policies are part of a white supremacist agenda," he said.

Travel ban 3.0 is set to take effect eight days after the Supreme Court is scheduled to hear oral arguments about the constitutionality of Trump's second travel ban. In June, the Supreme Court temporarily reinstated parts of that ban impacting travel from Iran, Libya, Somalia, Syria, Sudan, and Yemen, with the significant, albeit confusing, exclusion of "foreign nationals who have a credible claim of a bona fide relationship with a person or entity in the United States."

Sunday's announcement did not address refugee restrictions. Trump's second travel ban barred refugees for 120 days, and is set to expire on October 24th. Politico reports that the White House is planning to announce a refugee cap this week, to take effect October 1st.

The New York Immigration Coalition is planning to travel to Washington D.C. on October 10th to rally outside the Supreme Court during oral arguments on the second iteration of the travel ban.

[Update 2:00 p.m.]: The Supreme Court has canceled its October 10th oral arguments on the constitutionality of the second iteration of Trump's travel ban, in response to Trump's Sunday proclamation. All parties have been called on to present ten-page briefs on "whether, or to what extent, the Proclamation issued on September 24, 2017, may render cases... moot," due October 5th.

The legal argument agains the Muslim ban has been that it violates freedom of religion protections in the First Amendment.
