Donald Trump is set to ban people from 43 countries from travelling to the US

Those included under the 'red' label were reportedly Afghanistan, Bhutan, Cuba, Iran, Libya, North Korea, Somalia, Sudan, Syria, Venezuela and Yemen.

The 'red' categorisation means that citizens of these countries would be banned from entering the US.

The 'orange' category, however, would heavily limit visas, and the 'yellow' list would give citizens 60 days to address concerns.

In many cases, those from an 'orange' country would be able to enter the US if they are wealthy. However, tourist or immigrant visas would be tricky to get.

'Orange' countries include: Belarus, Eritrea, Haiti, Laos, Myanmar, Pakistan, Russia, Sierra Leone, South Sudan and Turkmenistan.

The 'yellow' list includes: Angola, Antigua and Barbuda, Benin, Burkina Faso, Cambodia, Cameroon, Cape Verde, Chad, the Republic of Congo, the Democratic Republic of Congo, Dominica, Equatorial Guinea, Gambia, Liberia, Malawi, Mali, Mauritania, St. Kitts and Nevis, St. Lucia, São Tomé and Príncipe, Vanuatu and Zimbabwe.

Trump's proposed travel ban would be an expansion of the 'Muslim ban' that he implemented during his first term as US President.

He introduced a number of executive orders aimed at barring people from Muslim majority countries from entering the US.

Officials told the New York Times, on the condition of anonymity, that the State Department had developed the list of 43 countries several weeks ago.

Changes to the list are highly likely before it reaches the White House, the sources said.
