The Department of Justice has filed a notice to appeal against the ruling by a Seattle court which suspended Donald Trump’s immigration ban imposed on travellers from seven Muslim-majority countries and put a temporary halt on refugee entry to the US.
The appeal has been lodged with the Ninth Circuit Court of Appeals, which has been asked to set aside the ruling by federal Judge James Robart, a George W. Bush appointee.
Visa holders from the affected nations have been scrambling to get flights to the US, fearing they have a slim window to enter America.
Mr Trump’s ban last week led to mass protests and confusion at US airports.
There were further demonstrations on Saturday in Washington, Miami and other US cities as well as in a number of European capitals.
Thousands of people turned out in London, with smaller protests in Paris, Berlin, Stockholm and Barcelona.
Trump supporters staged some counter-protests in the US.
Some 60,000 visas have been revoked since Mr Trump’s executive order was issued.
But Judge James Robart’s temporary restraining order halted it nationwide with immediate effect.
He found that legal challenges launched by two states, Washington and Minnesota, were likely to succeed.
Mr Trump called Judge Robart’s ruling “ridiculous”, vowing to restore the ban.
The ban envisages a 90-day visa suspension for anyone arriving from Iraq, Syria, Iran, Libya, Somalia, Sudan and Yemen.
The directive also suspends the US Refugee Admissions Programme for 120 days, and places an indefinite ban on Syrian refugees.
