President Trump has signed a presidential proclamation with new restrictions on travel to the United States as his existing ban on visitors from six Muslim-majority countries was set to expire Sunday, 90 days after it went into effect, according to senior administration officials.

On a background call about the new restrictions, the officials said restrictions will apply to Chad, Iran, Libya, North Korea, Syria, Venezuela, and Yemen, which have all been deemed to have "inadequate" identity-management protocols, information-sharing practices, and risk factors. The U.S. is implementing travel limitations and restrictions unique to the foreign nationals of each country. 

Acting Homeland Security Secretary Elaine Duke also assessed that Iraq did not meet the baseline but concluded that entry restrictions and limitations under a the proclamation are not warranted. Duke, according to officials, recommended that nationals of Iraq who seek to enter the United States be subject to additional scrutiny to determine if they pose risks to the national security or public safety of the U.S.

According to officials, the U.S. is easing restrictions on Iran, Libya, Syria, Yemen and Somalia and removed restrictions on Sudan altogether. And it added new restrictions or additional vetting of four new countries found not to be in compliant with U.S. vetting procedures -- Chad, Iraq, North Korea and Venezuela.

The restrictions on individuals and new countries covered by executive order will not be implemented immediately, They'll take effect October 18, in what senior administration officials called a "phased-in implementation period."

The new order is intended to enhance vetting capabilities and processes for detecting entry to the U.S. by terrorists, as well as other public safety threats.

Countries that were not already in compliant with the administration's protocols were given 50 days to make improvements.

The officials said that those individuals who are covered by the previous executive order that the president signed but do not benefit from court ordered exceptions will be covered from the time of signature of the proclamation Sunday. The restrictions 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.

Senior administration officials say that the ban is currently "condition-based and not time-based," so countries may come off the restricted list at some point. Conversely, DHS may also recommend new countries to the list as they closely monitor necessary compliance. The citizens of countries that refuse to comply with DHS requirements can now face travel restrictions and more stringent screening measures that would last indefinitely, until their governments comply.
