Canada's immigration minister has been holding a press conference - where he announced his country will offer temporary residency to those stranded in Canada as a result of the turmoil in the US.

However, he told assembled press that the impact of the order in Canada has been "minimal".

The BBC's Olivia Lace-Evans has been to Republican-leaning Staten Island, New York City, to hear from people on the street what they think of President Trump's order.

In November's presidential election, Trump carried 57% of the vote in this borough, compared to Hillary Clinton's 40%.

British Foreign Secretary Boris Johnson has held conversations with the US government.

The UK Foreign Office later issued this advice, external to British travellers.

It says that dual citizens are only affected if travelling to the US from one of the seven countries named in the order - Iraq, Syria, Iran, Libya, Somalia, Sudan, and Yemen.  

However, one Scottish veterinary student - who travels on an Iranian passport - was unable to fly home from her holiday in Costa Rica because she was told her transit visa for the US was no longer valid.

A green card-holding Syrian musician who is currently on a world tour is wondering if he will be allowed to return to his Brooklyn home.

Kinan Azmeh, a clarinet player who has called the US home for 16 years, said on Sunday he does not have a "plan B" if denied re-entry.

The 40-year-old, who is now on the last leg of his tour in Beirut after performing with famed cellist Yo-Yo Ma in China and Denmark, said: "I have my apartment. 

"You know, 16 years is not a short time, you accumulate lots of stuff. But what is not replaceable is all the friends who are incredibly supportive." 

He was granted a green card three years ago through an EB-1 visa, for applicants who can demonstrate "extraordinary ability" in science, business or art.

The conservative Koch political network - a mega-donor to the Republican party, with strong links to the Trump administration - has denounced the new president’simmigration order.

Spokesman Brian Hooks said in a statement: "The travel ban is the wrong approach and will likely be counterproductive. We believe it is possible to keep Americans safe without excluding people who wish to come here to contribute and pursue a better life for their families."

The statement came as the Koch network gathered for its conference in Palm Springs, California.

The chief lawyers in 16 US states have issued a joint statement condemning the order. 

Attorneys general from California, New York, Pennsylvania and 13 other states said: "We are committed to working to ensure that as few people as possible suffer from the chaotic situation that it has created."

Ali worked for three years as an interpreter for the US Army and gained admittance to the US through a Special Immigrant Visa, reserved for Iraqi and Afghan nationals who face threats of violence for working for Americans during the conflicts there.

He now has a green card, and returned to Iraq for his father's funeral, only to be delayed for hours for questioning at Dulles.

"We are not terrorists. We are not bad people," said Ali. "It's so hard. I hope they will change their minds on this position."

The BBC's Jessica Lussenhop also witnessed this moment, an Iraqi couple at Dulles presented with a Purple Heart by a well-wisher and his son:

President Trump's spokespeople have been defending the executive order on the Sunday shows.

Senior adviser Kellyanne Conway told Fox News Sunday: "325,000 people from overseas came into this country just yesterday through our airports. 

"You’re talking about 300-and-some who have been detained or are prevented from gaining access to an aircraft in their home countries and must stay for now. That’s 1%, and I think in terms of the upside being greater protection of our borders of our people, it’s a small price to pay." 

White House chief of staff Reince Priebus told NBC's Meet the Press the order would keep out "people who want to do bad things to America".

But Mr Priebus also caused confusion over whether the order affects green card holders.

He first told NBC’s Chuck Todd it "doesn't include green card holders going forward".

But when pressed later in the interview on whether the order covers those with permanent US residency status, he said: "Well, of course it does."

A North Carolina college professor and Iranian dissident, Mohsen Kadivar, fears he will not be allowed back into the US to rejoin his wife and two children after travelling to Germany a week ago to attend a fellowship programme until July.

Mr Kadivar told Reuters news agency from Berlin: "I am concerned about my future. I don't know whether I will be able to return to the United States as a green card holder Iranian national."

The Duke University lecturer was once a supporter of Iran's 1979 Islamic revolution, but later fell foul of its leaders.

The director of an Iranian film which is up for Oscars glory has said he will not attend the ceremony because of the travel ban.

Asghar Farhadi, nominated for best foreign-language film for The Salesman, said on Sunday the questions over his entry to the US made it unacceptable for him to come.  

Earlier, Academy Awards organisers said it was "extremely troubling" that his attendance was in doubt.

Meanwhile, one of California's other main industries, tech, has also expressed deep unease at the Trump travel ban.

Google has told the BBC it is concerned about the order and the impact on foreign talent coming to the US. It has instructed travelling staff members to return to the US.

Other Siicon Valley giants such as Facebook and Microsoft have also tried to safeguard employees, Politico reports., external

A petition is circulating demanding that President Trump's invitation for a UK state visit be withdrawn "because it would cause embarrassment to Her Majesty the Queen", external.

It has already reached over half a million signatures. 

Only 100,000 names are needed for Parliament to consider holding a debate, meaning this one could be discussed by MPs.

Readers will remember the House of Commons in January 2016 debated calls for Trump to be denied entry to the UK after an earlier petition drew nearly 570,000 signatures, following the then-US presidential candidate's comments calling for Muslims to be banned from the US. A rival petition opposing a ban on Trump was signed by nearly 40,000 people.

While the US liberal-leaning media has been united in outrage to President Trump's executive action, the conservative media have welcomed it.

Conservative blog Red State hits out, external at former Democratic presidential candidate Hilary Clinton, pointing to an ABC News report that while she was Secretary of State in 2011 the State Department stopped processing Iraqi refuges for six months after the discovery two years earlier of two al Qaeda militants living as refugees in Bowling Green, Kentucky, who admitted in court that they had attacked US soldiers in Iraq.

"I know that there have been rumors about Mrs. Clinton’s memory. But has Hillary Clinton really forgotten that President Obama ordered a similar ban on travel from Iraq, in 2011, when She was Secretary of State? Her hypocrisy knows no bounds."  

Breitbart has an op-ed, external from former vice-presidential candidate Sarah Palin: 

"Trump is doing what the majority recognized was necessary to secure our borders. Voters asked for it, he promised it, and thus he was elected. Now he’s doing it.

"This isn’t inhumane. It’s exercising common-sense compassion to keep human beings safe. It’s about fully vetting foreigners and merely following the laws the people - through our representative form of government within our republic - agreed upon.

"The misinformed are ballistically knee-jerking because they aren’t used to candidates fulfilling campaign promises. Perhaps it’s shocking because we’re used to swamp dwellers murkying up the waters once typical politicians get elected, but that’s exactly why a typical politician wasn’t elected. The status quo has got to go."

These rulings are only the opening salvo in what will likely be a protracted legal battle, as the Trump administration forges ahead with its plans.

The episode has made the White House look amateurish and ill-prepared, however, and Republicans in Congress are getting nervous.

During the presidential primaries, a majority of Republican voters backed Mr Trump's calls for a sweeping ban on Muslims entering the US. During the general election, he campaigned on a visa ban for certain "terrorist" countries - and won.

So it shouldn't come as much of a surprise if the president's core support holds firm after this weekend's events. The views in the American heartland, far removed from major international airports, sometimes differ greatly from the liberal bastions on the coast.

However, protracted airport detention of children and the elderly is "bad optics" - and could make it harder for the White House to get public support for future immigration action.
