Donald Trump has banned people from 12 countries entering the US, in a move he said protects against "foreign terrorists" and other security threats.
Some countries are subject to a full travel ban, while others are under a partial ban - with the order allowing countries to be removed or added from the list.
The proclamation is due to come into effect just after midnight on 9 June local time.
The ban echoes one in 2017 that Mr Trump implemented in his first term in the White House. This banned citizens from seven predominantly Muslim countries - Iraq, Syria, Iran, Sudan, Libya, Somalia and Yemen - from travelling to the US.
