The Trump administration is considering issuing sweeping travel restrictions for the citizens of dozens of countries as part of a new ban, according to sources familiar with the matter and an internal memo seen by Reuters.

The memo lists a total of 41 countries divided into three separate groups. The first group of 10 countries, including Afghanistan, Iran, Syria, Cuba and North Korea among others, would be set for a full visa suspension.

In the second group, five countries – Eritrea, Haiti, Laos, Myanmar and South Sudan – would face partial suspensions that would impact tourist and student visas as well as other immigrant visas, with some exceptions.

In the third group, a total of 26 countries that includes Belarus, Pakistan and Turkmenistan among others would be considered for a partial suspension of U.S. visa issuance if their governments “do not make efforts to address deficiencies within 60 days”, the memo said.
