The administration of U.S. President Donald Trump 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 reporters.

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.
