US President Donald Trump's administration is considering imposing sweeping travel restrictions on citizens of dozens of countries as part of a new ban, according to sources familiar with the matter and an internal memo that has come into the possession of Reuters.

The memo lists 41 countries, divided into three separate groups. The first group of 10 countries, including Afghanistan, Iran, Syria, Cuba and North Korea, would have their visas completely revoked.

In the second group, five countries will face partial visa suspensions that will affect tourist and student visas, as well as other immigration visas, with some exceptions.

In the third group, 26 countries would be considered for partial suspensions of U.S. visas if their governments “do not make efforts to correct deficiencies within 60 days,” the memo said.

A U.S. official, who spoke to Reuters on condition of anonymity, warned that the list was subject to change and had yet to be approved by the administration, including U.S. Secretary of State Marco Rubio.

The move is reminiscent of President Donald Trump's first-term ban on travelers from seven Muslim nations entering the country.

On Jan. 20, Trump issued an executive order requiring enhanced security screening of all foreigners seeking to enter the U.S. to identify national security threats.

The decree orders several cabinet members to submit by March 21 a list of countries from which travel should be partially or fully suspended because “the information on their screening and inspection is so incomplete.”
