"It's like the United States doesn't actually understand what I did for this country, it's a betrayal," Abdullah tells the BBC.

He fled Afghanistan with his parents amid the US withdrawal in August 2021 and is now a paratrooper for the US military. He worries he can't help his sister and her husband escape too, because of President Donald Trump's executive order suspending a resettlement programme.

The order cancels all flights and suspends applications for Afghan refugees, without any exemption for families of active servicemembers.

Trump argues the decision addresses "record levels of migration" that threaten "the availability of resources for Americans".

But Abdullah and several other Afghan refugees have told the BBC they feel the US has "turned its back" on them, despite years of working alongside American officials, troops and non-profit organisations in Afghanistan. We are not using their real names, as they worry doing so could jeopardise their cases or put their families at risk.

As soon as Abdullah heard about the order, he called his sister in Afghanistan. "She was crying, she's lost all hope," he said. He believes his work has made her a target of the Taliban government which took power in 2021.

"The anxiety, it's just unimaginable. She thinks we'll never be able to see each other again," he says.

During the war, Abdullah says he was an interpreter for US forces. When he left Afghanistan, his sister and her husband couldn't get passports in time to board the flight.

Suhail Shaheen, a spokesperson for the Taliban government, told the BBC there is an amnesty for anyone who worked with international forces and all Afghans can "live in the country without any fear". He claims these refugees are "economic migrants".

But a UN report in 2023 cast doubt on assurances from the Taliban government. It found hundreds of former government officials and armed forces members were allegedly killed despite a general amnesty.

Abdullah's sister and her husband had completed the medical exams and interviews required for resettlement in the US. The BBC has seen a document from the US Department of Defense endorsing their application.

Now Abdullah says Trump's insistence that immigration is too high does not justify his separation from his family. He describes sleepless nights, and says the anxiety is affecting his work in his combat unit, serving the United States.

Babak, a former legal adviser to the Afghan Air Force, is still in hiding in Afghanistan.

"They're not just breaking their promise to us - they're breaking us," he says.

The BBC has seen letters from the United Nations confirming his role, as well as a letter endorsing his asylum claim by a Lt Colonel in the US Air Force. The endorsement adds that he provided advice on strikes targeting militants linked to both the Taliban and the Islamic State group.

Babak can't understand the president's decision, given that he worked alongside US troops. "We risked our lives because of those missions. Now we're in grave danger," he says.

He has been moving his wife and young son from location to location, desperately trying to stay hidden. He claims his brother was tortured for his whereabouts. The BBC cannot verify this part of his story, given the nature of his claims.

Babak is appealing to Trump and his National Security Adviser Mike Waltz to change their minds.

"Mike Waltz, you served in Afghanistan. Please encourage the president," he tells us.

Before saying goodbye, he adds: "The one ray of light we've been holding onto has been extinguished."

Ahmad managed to fly out to the US amid the chaos of the withdrawal but is now separated from his family. He felt he had no choice but to leave his father, mother and teenage siblings behind.

If he and his father had not worked with the US, he says, his family would not be targets of the Taliban government. "I can't sleep knowing I'm one of the reasons they're in this situation," he adds.

Before the Taliban takeover, Ahmad worked for a non-profit called Open Government Partnership (OGP), co-founded by the US 13 years ago and headquartered in Washington. He says the work he's proudest of is establishing a special court to address abuses against women.

But he claims his work at OGP and his advocacy for women made him a target and he was shot by Taliban fighters in 2021 before the Taliban took over the country.

The BBC has seen a letter from a hospital in Pennsylvania assessing "evidence of injury from bullet and bullet fragments" which they say is "consistent with his account of what happened to him in Kabul".

Making matters worse, he says his family is also in danger because his father was a colonel with the Afghan army and assisted the CIA. The BBC has seen a certificate, provided by the Afghan National Security Forces, thanking his father for his service.

Ahmad says the Taliban government has harassed his parents, brothers and sisters, so they fled to Pakistan. The BBC has seen photos showing Ahmad's father and brother being treated in a hospital for injuries he claims were inflicted by people from the Taliban government.

His family had completed several steps of the resettlement programme. He says he even provided evidence that he has enough funds to support his family once they arrive in the US, without any government help.

Now Ahmad says the situation is critical. His family are in Pakistan on visas that will expire within months. He has contacted the IOM and has been told to "be patient".

The head of #AfghanEvac, a non-profit group helping eligible Afghan refugees resettle, said he estimated 10,000-15,000 people were in the late stages of their applications.

Mina, who is pregnant, has been waiting for a flight out of Islamabad for six months. She worries her terror will threaten her unborn child. "If I lose the baby, I'll kill myself," she told the BBC.

She says she used to protest for women's rights, even after the Taliban government took control of Afghanistan. She claims she was arrested in 2023 and detained overnight.

"Even then I didn't want to leave Afghanistan. I went into hiding after my release, but they called me and said next time, they'd kill me," she says.

Mina worries the Pakistani government will send her back to Afghanistan. That's partly because Pakistan will not grant Afghan refugees asylum indefinitely.

The country has taken in hundreds of thousands of refugees from its neighbour, over decades of instability in the region. According to the UN refugee agency, the country hosts three million Afghan nationals, about 1.4 million of whom are documented.

As cross-border tensions with the Taliban government have flared, there has been growing concern over the fate of Afghans in Pakistan, with reports of alleged intimidation and detentions. The UN special rapporteur has said he's concerned and Afghans in the region deserve better treatment.

Pakistan's government says it is expelling foreign nationals who are in the country illegally back to Afghanistan and confirmed search raids were conducted in January.

According to the IOM, more than 795,000 Afghans have been expelled from Pakistan since September 2023.

The Afghan refugees we've spoken to feel caught between a homeland where their lives are in danger, and a host country whose patience is running out.

They had been pinning their hopes on the US - but what seemed a safe harbour has been abruptly blocked off by the new president until further notice.
