A US judge has issued a temporary halt to the deportation of visa holders or refugees stranded at airports following President Trump’s executive order.
The American Civil Liberties Union (ACLU) filed a case in response to the order issued on Friday.
The ACLU estimates that between 100 and 200 people are being detained at airports or in transit.
Thousands of people have been protesting at US airports over Mr Trump’s clampdown on immigration.
His executive order halted the entire US refugee programme and also instituted a 90-day travel ban for nationals from Iran, Iraq, Libya, Somalia, Sudan, Syria and Yemen.
Those who were already mid-flight were detained on arrival – even if they held valid US visas or other immigration permits.
On Saturday, Mr Trump told reporters: “It’s working out very nicely. You see it at the airports, you see it all over.”
Other executive orders issued by Mr Trump on Saturday were:
- A ban on administration officials ever lobbying on behalf of a foreign government
- An order to Defense Secretary Jim Mattis to come up with a plan within 30 days to defeat so-called Islamic State
- Restructuring the National Security Council with a key role for senior strategist Steve Bannon
