In a conference call at around 9 pm local time, the US agency told airlines to operate just as they had before the order, which temporarily had stopped refugees and nationals from seven Muslim-majority countries from entering the United States. Individuals from those states who have proper visas can now board US-bound flights, and airlines are working to update their websites to reflect the change, said the official, who was not authorized to speak publicly.
The judge's temporary restraining order represents a major challenge to US President Donald Trump's action, although his administration could still appeal the ruling and have the policy upheld.
Judge James Robart, a George W Bush appointee, made his ruling effective immediately on Friday, suggesting that travel restrictions could be lifted straight away. He is expected to issue a full written ruling over the weekend.
CBP and Washington-based trade group Airlines for America did not immediately comment.
