The White House is expected to unveil a new entry ban executive order today, according to senior US administration officials.
The order is expected to be a revised version of an entry ban that US President Donald Trump signed in January, which has been blocked by a federal court.
Mr Trump has met with Attorney General Jeff Sessions and Department of Homeland Security Secretary John Kelly - both central to the implementation of the order - at his Mar-a-Lago resort.
White House officials have said that the new order will address some of the legal concerns raised by federal judges.
"Fundamentally, you're still going to have the same basic policy outcome for the country," White House senior policy adviser Stephen Miller said on Fox News last month.
"But you're going to be responsive to a lot of very technical issues that were brought up by the court."
Mr Trump's first order blocked immigration from seven predominantly Muslim countries: Iraq, Syria, Iran, Sudan, Libya, Somalia and Yemen.
Critics called the order a de facto "Muslim ban".
Trump administration officials have promised to continue defending the original order in courts, even while the president is expected to sign a new order. (© The Washington Post)
