The Department of Homeland Security has recommended the president sign off on new, more targeted restrictions on foreign nationals from countries it says refuse to share information with the U.S. or haven't taken necessary security precautions.

Officials haven't said whichor how many countries willbe affected by the new restrictions, which could take effect as soon as Sunday.

"The acting secretary has recommended actions that are tough and that are tailored, including restrictions and enhanced screening for certain countries," said Miles Taylor, counsellor to acting Homeland Security Secretary Elaine Duke.

The current ban bars citizens of Iran, Libya, Somalia, Sudan, Syria and Yemen who lack a "credible claim of a bona fide relationship with a person or entity in the United States" from entering the U.S.

Countries asked to hand over information

The recommendations are based on a new baseline developed by Homeland Security that includes factors such as whether countries issue electronic passports with biometric information and share information about travellers' terror-related and criminal histories. The U.S. then shared those benchmarks with every country in the world and gave them 50 days to comply.

The citizens of countries that refused could face travel restrictions and more stringent screening measures that would last indefinitely, until their governments complied.

In June, the U.S. Supreme Court allowed alimited version of Trump's ban on travel to take effect. After the decision was released, Canadian Prime Minister Justin Trudeausaidhe wouldcontinue to promote Canada's open immigration policy on the world stage.

Trump last week called for a "tougher" travel ban aftera bomb partially explodedon a London subway.

"The travel ban into the United States should be far larger, tougher and more specific —but stupidly, that would not be politically correct!" he tweeted.

Critics have accused the president of overstepping his authority and violating the U.S. Constitution's protections against religious bias. Trump had called for a "total and complete shutdown of Muslims entering the United States" during his campaign on the road to the presidency.
