Refugees and immigrants from Muslim majority war-torn countries are being detained at American airports or blocked from boarding flights to America as President Donald Trump’s immigration executive order takes effect.

CNN reported that Trump’s immigration ban temporarily blocks 130 million people from theoretically entering the United States.

Those impacted by the order included Hameed Darweesh, an Iraqi man who helped the U.S. military as an interpreter in Iraq (although he was later freed) and a woman trying to visit her cancer-stricken mother. Green card holders, Canadian citizens, and Google staff members are among those impacted.

President Trump, in signing the executive order, said it was necessary to weed out Islamic radical terrorists who might come to America to cause harm. However, there were already reports on January 28 – the day after the order – that those affected might include an Iranian filmmaker whose film was nominated for an Academy Award and employees of Google. Many people were also confused about whether they or loved ones would be affected by the order and how.

According to CNN, Trump’s order bans “citizens of Iraq and six other Muslim-majority countries – a total of at least 134 million people – from entering the US for the next 90 days. It also suspends the admission of all refugees for 120 days.” CNN reported that the ban affects “students and legal US residents who are citizens of the seven countries banned by Trump and are now stuck overseas.”

The affected countries are Iran, Iraq, Libya, Somalia, Syria, Sudan and Yemen. Immigration from all but Syria was temporarily suspended; Syrian immigration was indefinitely suspended. There are narrow exemptions that can be granted in some cases.

Protests were scheduled for airports around the United States.

Lawyers filed suit on behalf of two Iraqi men detained, including Darweesh, and are seeking to turn the suit into a class action that alleges Trump’s executive order singles out Muslims and is unconstitutional. The lawsuit alleges, “Petitioners’ continued unlawful detention is part of a widespread pattern applied to many refugees and arriving aliens detained after the issuance of the January 27, 2017 executive order.”

The lawyers are alleging violations of the due process clause of the 5th and 14th Amendments. The lawsuit says, “Under United States law as well as human rights conventions, the United States may not return…a noncitizen to a country where she may face torture or persecution.”

Here’s a round up of those detained or impacted as a result of the order:

Dallas & JFK Airport Detainments

Protests erupted at John F. Kennedy airport in New York after reports of detainments.

Rep. Jerry Nadler, of New York, wrote on Twitter that he was working to help 11 refugees detained. That’s in addition to two other Iraqi men who were held at JFK after their flights landed (their cases will be explained in the next two sections).

In Dallas, local news reports said as many as 50 people were detained with families crying at the airport.

Canadian Citizens

City News reported: “Canadians who hold dual citizenship with any of the seven countries targeted by a travel ban will not be permitted to enter the U.S., a representative from the State Department said Saturday.”

Google Employees

Google ordered its employees traveling overseas who are from countries affected by the ban to return to the United States, according to Fortune.

The action affected 100 staff members of the tech giant.

Green Card Holders

According to CNN, “The US government will not automatically allow green card holders who traveled to countries placed under a temporary travel ban back into the United States.”

Such travelers must apply for a waiver to the executive order.

Hameed Darweesh

Darweesh was detained at John F. Kennedy airport in New York on January 27.

According to CNN, Darweesh was released due to exemptions in Trump’s order “that allow the State and Homeland Security departments to admit individuals into the US on a case-by-case base for certain reasons, including when the person is already in transit and it would cause undue hardship and would not pose a threat to the security of the US.”

The lawsuit says that Darweesh is an Iraqi husband and father of three. He is 53-years-old, and his children are ages 20, 15, and 7, according to the suit.

The lawsuit says that Darweesh was previously targeted while in Iraq for his service to the United States military.

The lawsuit says that Darweesh worked as an interpreter for the U.S. Army 101st Airporne in Baghdad and Mosul in 2003 and 2004; worked as an interpreter for the 91st Engineering Unit at the Baghdad Airport in 2004; worked as a Project Engineer for the U.S. Government Projects Contracting Office Oil Sector of North Iraq in 2005 and 2006; and worked for the U.S. government’s Vessar contractors from 2006 to 2011.

In one incident, the lawsuit contends, while working at the Baghdad Airport, the Baghdad police – known to be affiliated with anti-American militias – entered Darweesh’s home and said they were looking for a terrorist. When two of his co-workers were then killed, Darweesh feared for his safety and left Baghdad for Kirkuk, the lawsuit contends. On another occasion, men in a BMW whom Darweesh believes were terrorists twice asked local shopkeepers where he lived. Fearing again for his safety, he fled Kirkuk to Erbil. He then decided to apply for a visa to come to the United States.

Haider Sameer Abdulkhaleq Alshawi

Those working on behalf of Darweesh also filed suit in the name of Alwashi, an Iraqi man who was seeking to join his wife and young son in America.

According to the lawsuit, Alshawi was granted a Follow to Join Visa on January 11, 2017 to rejoin his wife and son, who were granted refugee status due to their family’s association with the United States military.

Alshawi’s wife had worked for a U.S. contractor, the Independent reported.

The lawsuit says that Alshawi’s wife and son were resettled in Houston, Texas.

Alshawi graduated with an accounting degree in 2006 from Baghdad University. Alshawi and his wife Duniyya Alshawi have been married since 2008.

Alshawi’s wife worked for Falcon Security Group, a U.S. contractor, from 2006 to 2007 as an accountant, the lawsuit says. Her brother worked for the contractor as an accountant as well.

According to the lawsuit, “Mr. Alshawi heard through neighbors in the family’s community in Baghdad that, due to the family’s association with the U.S. military, insurgents thought that they were collaborators.” Members of his extended family were blown up by insurgents with an IED, the lawsuit said.

Stopped in Cairo

Seven people – from Iraq and Yemen – were detained at the Cairo airport, according to ABC News.

Sahar Alghnimi – Going to Visit Her Cancer-Stricken Mother

ABC News reported that a Syrian woman, Sahar Alghnimi, was detained in Chicago, where she had arrived to see her mother, who was being treated for cancer. She was sent back to Saudi Arabia, reported ABC.

Asghar Farhadi – Oscar Nominated Filmmaker From Iran

Daily Variety reported that the executive order may prevent Iranian filmmaker Asghar Farhadi from attending the 2017 Academy Awards; he “wrote and directed the 2017 Oscar-nominated foreign language film ‘The Salesman,’” Variety reported.

Farhadi already won an Oscar for 2011’s A Separation, and when he accepted that award, he famously acknowledged how politics had kept Iranian culture hidden from the world.

Other Reports on Social Media

Other accounts were coming in on social media, although they were not yet verified.

The Washington Post reported that a refugee family might be detained at San Francisco airport too.

Reza Zadeh – Stanford University Professor

A Stanford professor said that he was affected by the executive order:

The professor wrote that he was already in the U.S. “The US is my home & am happy here. Currently in the US & postponing international trips, hoping the situation clears,” he said on Twitter. Asked by a reporter if he was outside the U.S., he wrote: “No I am inside US and trapped essentially.”
