Donald Trump is considering issuing sweeping travel restrictions on citizens from 43 countries as he continues his immigration crackdown.

An internal US government memo shows the countries divided into three categories, labelled red, orange and yellow.

The red group, comprising 11 countries, would face the most severe restrictions – a complete ban on their citizens entering the United States. They include Afghanistan, Cuba, Iran, Syria and Venezuela.

Countries in the second category – including Belarus, Russia, Pakistan and Haiti – would see their visas sharply restricted. According to the New York Times, which first reported the proposals, affluent business travellers from these countries might still be allowed to enter, but not people travelling on immigrant or tourist visas.

Citizens in this category would also be subjected to mandatory in-person interviews in order to receive a visa.
