Mothers carrying their children smile, give me a thumbs up, and then point to a riverbank 50 metres or so away.
We’re on a walkway bridge between the Mexican city of Matamoros and Brownsville in Texas. The riverbank is of course the United States – so close you feel you can almost touch it.
For these families wide-eyed with excitement, this is the moment they’ve dreamt of. Many have endured months, even years, on the road.
Sometimes travelling thousands of miles through hostile countries, outwitting cartel gangs, and managing dizzyingly contradictory bureaucracy, all to get to this point: an asylum interview with United States border officials, and almost certain entry.
On its face, this all sounds like a system working in perfect harmony with the needy being helped by a welcoming country.
But in reality, migration is a hotly disputed issue that is likely to dominate the Trump-Harris debate, and the run-up to the presidential election itself.

The group I am with on the bridge is mostly from Cuba, Nicaragua, Haiti, and Venezuela.
They’re claiming asylum, and with their paperwork and appointment email in hand, they approach the border with some trepidation but mostly with excitement and joy.
Many have waited months for their appointment to come through after applying for asylum on the US Customs and Border Protection (CBP) app.
This group of a few hundred people on the bridge are now just a few steps from America.
As they shuffle forward, CBP guards check their papers, make sure there are no errors, and wave them through to the other side for their case interviews.
These families, these children, are about to start a new life.
Along the border here in Matamoros, there’s little sign of Donald Trump’s border wall, but he’d doubtless approve of the razor wire fortifications on the American side of the Rio Grande.
Experts here say there’s no doubt who those seeking asylum are backing in this election and this debate – and that’s Kamala Harris, who is seen to have a far less hostile approach to immigration.
“I think the best would be a flexible US immigration policy again, like President Biden’s when he began his administration,” Oscar Misael Hernandez-Hernandez said as we chatted alongside the dozens of cars and trucks crossing the border.

A professor of social anthropology at the El Colegio de la Frontera Norte research centre and an expert on Mexico-US border issues, he added: “Biden broke with ultra-conservative vision and immigration policy.
“So, I think if Harris implements a migration policy like this if she wins the presidency of the United States, it would be not only quite good for migrants in terms of human rights, but also quite good for international diplomacy, because the relations of the United States, at least with President Trump, if he wins, would be quite disastrous as they were in the past.”
In shelters and hostels across Mexico, many other migrant families simply have to wait for their border appointments.
It’s like a lottery, and it can take a long time for their number to come up.
Few leave the shelter; they would be easy prey for cartel gangs who would kidnap and hold them for ransom.

Any tightening of the immigration rules – as threatened by Donald Trump – would be a disaster for her.
I asked her what she would do if the laws changed with a Trump victory. She says she doesn’t like to think about what-ifs.
“I’ve been here so long, and not being able to get in would be hard because it’s the only option I have,” she said.
“I have to get in. It would be really terrible if we couldn’t. And I don’t just speak for myself, I speak for everyone here.”
Jose Valdivia, the Nicaraguan manager of the shelter, is even clearer.
“Everybody, since the last election, we all wanted the Democrats to win, right? Because the Democrats look out for the little guy,” he told me.
“That’s what everybody here as a migrant wants, we want the Democrats to win. No one wants Trump.”

Day in, day out, in any weather, the migrants line up for their appointment here at the border in Matamoros.
Along the almost 2,000-mile-long border separating Mexico and the United States, thousands of applicants are screened every day and allowed to enter America legally to start new lives in their new home country.
But these migrants are at the centre of one of the most divisive issues in America right now.
Since the summer, border restrictions introduced by the Biden administration, combined with assistance from Mexican authorities who hamper the movement of migrants to the border, has brought about a large reduction in the number of people illegally entering America.
Despite this, President Biden is widely considered to have failed on immigration, and while Kamala Harris’s team have been working hard to cast her as a sort of new candidate and a breath of fresh air, she is – whether they like it or not – part of this administration and is tainted by its perceived failures.
The latest polls suggest Donald Trump scores well on the immigration issue, and his team have been releasing pointed “attack ads” on Kamala Harris and her team on this subject. They in turn have released adverts attacking Trump.
In the debate itself, Trump is widely expected to try to nail Harris on immigration, and she will have to find a way to counter that.
Undoubtedly, she will point out that Trump’s supporters kiboshed a cross-party action plan for migration, but she is still tainted for certain.
While this will all play out in the political rough and tumble of the electoral process, it is important not to forget that thousands upon thousands of people will be affected by America’s future stance on immigration.
And for some asylum seekers, it is quite literally a matter of life and death.
US President Donald Trump has called for the reopening of notorious prison Alcatraz.
In a post on his social media site Truth Social, Mr Trump said America had been “plagued by vicious, violent, and repeat criminal offenders”.
He added that when the United States was “a more serious nation” it “did not hesitate to lock up the most dangerous criminals”.
“That is why, today, I am directing the Bureau of Prisons, together with the Department of Justice, FBI, and Homeland Security, to reopen a substantially enlarged and rebuilt Alcatraz, to house America’s most ruthless and violent offenders,” he wrote.
Mr Trump said the reopening of the San Francisco prison would “serve as a symbol of law, order, and justice”.

Alcatraz was infamously inescapable and in the 29 years it was open, 36 men attempted 14 separate escapes, according to the FBI.

Nearly all of them were caught or did not survive the attempt at escaping.
The prison housed some of America’s most notorious criminals, including Al Capone and George Kelly.
It has also been the subject of a number of films, including The Rock, starring Sean Connery and Nicolas Cage.

Alcatraz Island, which is surrounded by strong ocean currents and cold Pacific waters, is now a major tourist site, operated by the National Park Service.
The prison’s closure in 1963 was attributed to crumbling infrastructure and high repair costs.
A spokesperson for the Bureau of Prisons said it would “comply with all presidential orders”.
The Bureau of Prisons currently has 16 high-security prisons, including its maximum-security facility in Florence, Colorado, and a facility in Terre Haute, Indiana, which is home to the federal death chamber.
The United States’ federal law enforcement agency has been the subject of increased scrutiny in recent years after Jeffrey Epstein‘s suicide at a federal jail in New York City in 2019.
A woman in the US who has been missing since 1962 has been found “alive and well”, authorities have said.
Audrey Backeberg left her home in Reedsburg, Wisconsin, in July that year when she was 20 years old, Sauk County Sheriff’s Office said.
Investigators pursued numerous leads over the years but the case eventually went cold.
However, during a review of cold cases earlier this year, a detective reassessed all the case files and evidence, and re-interviewed several witnesses – and found Ms Backeberg.
The 82-year-old was “alive and well” – living outside of the state of Wisconsin, the sheriff’s office said.
Ms Backeberg was married and had two children when she disappeared on 7 July 1962, according to the Wisconsin Missing Persons Advocacy organisation.
She left her home to pick up her salary but never returned, causing her husband to ask family members where she was.
Shortly afterwards their 14-year-old babysitter claimed she and Ms Backeberg had hitchhiked to Wisconsin’s capital city Madison and then caught a bus to Indianapolis, Indiana.
The teenager said when she arrived she became nervous and wanted to go home, while Ms Backeberg refused to return and was last seen walking near a bus stop.
Ms Backeberg’s marriage was troubled and there were allegations of abuse, the Wisconsin Missing Persons Advocacy organisation said, with a criminal complaint having been filed days before she went missing.
Her relatives insisted she would never abandon her children, the organisation added, and her husband passed a polygraph test and maintained his innocence.
Mr Hanson said Ms Backeberg may have left home due to marital issues, but it was unclear why she had stayed away for so long.
He said he had promised to keep their conversation private.
“I think she just was removed and, you know, moved on from things and kind of did her own thing and led her life,” he said.
“She sounded happy. Confident in her decision. No regrets.”
Sauk County Sheriff’s Office said Ms Backeberg made the choice to leave and her disappearance “was not the result of any criminal activity or foul play”.
Donald Trump has posted an AI-generated image of himself dressed in papal regalia on his Truth Social platform – just 11 days after the death of Pope Francis.
Uploaded onto his account early on Saturday morning, it shows the US president with a large gold cross on a chain around his neck.
From there, it was published, without comment or explanation, on the White House X and Instagram accounts and, though it drew fierce criticism, it was liked more than 100,000 times.

It comes just a few days after the world leader joked that he’d like to be the pontiff.
Last week, he was asked by reporters on the White House lawn who he would like to succeed Francis and he replied: “I’d like to be Pope. That would be my number one choice.”
He went on to say that he did not have a preference, but there was a cardinal in New York who was “very good”.

‘I’d like to be pope’
Mr Trump was quickly accused of mocking Pope Francis’sdeath, but, by noon, UK time, the post had been liked more than 58,000 times on Instagram.
User comments, however, were mostly negative, with one saying that the image “isn’t funny. It’s not satire. And it’s not harmless”.
Another simply called it “disgusting”, while other reactions included “disturbing”, “disrespectful” and “offensive”.
On X, where the picture was liked more than 78,000 times, a user commented that Mr Trump was “making a mockery of the pious”, while another judged it “not a wise decision”.
The Argentinian, who became pope in 2013, died on Easter Monday at the age of 88 due to a stroke and heart failure.
Last weekend, the president was criticised for wearing a non-traditional blue suit for Francis’s Vatican funeral and chewing gum during the ceremony.
However, his meeting in St Peter’s Basilica with Ukrainian President Volodymyr Zelenskyy before the outdoor mass got under way was dubbed “Pope Francis’s miracle” by members of the clergy.

Mr Trump’s own religious views have long been a matter of speculation.
He was raised as a Presbyterian and publicly identified with it for most of his adult life, before, in October 2020, he renounced it and said he now considered himself a non-denominational Christian.
Many have questioned the depth of his faith, but that hasn’t stopped him appealing to conservative Christians and the Christian right, particularly evangelicals, some of whom have helped him get elected twice.

Earlier this year, Mr Trump shared a bizarre AI-generated video on his Truth Social platform showcasing what appeared to be a vision of Gaza under his proposed plan.
The footage showed the area transformed into a Middle Eastern paradise with exotic beaches, Dubai-style skyscrapers, luxury yachts and people partying – and featured Israeli Prime Minister Benjamin Netanyahu and Elon Musk.
