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.
Marlen Cabrera, 39, from Honduras, and her family are waiting it out along with 200 others at the Casa del Migrante San Francisco de Asis shelter.

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.
Donald Trump says he has ordered two nuclear submarines to be positioned in the “appropriate regions” in a row with former Russian president Dmitry Medvedev.
It comes after Mr Medvedev, who is now deputy chair of Russia‘s Security Council, told the US president on Thursday to remember Moscow had Soviet-era nuclear strike capabilities of last resort.
On Friday, Mr Trump wrote on social media: “Based on the highly provocative statements of the Former President of Russia, Dmitry Medvedev, who is now the Deputy Chairman of the Security Council of the Russian Federation, I have ordered two Nuclear Submarines to be positioned in the appropriate regions, just in case these foolish and inflammatory statements are more than just that.
“Words are very important, and can often lead to unintended consequences, I hope this will not be one of those instances. Thank you for your attention to this matter!”

Trump: ‘We’re going to protect our people’
Speaking outside the White House later in the day, Mr Trump was asked about why he had moved the submarines and replied: “We had to do that. We just have to be careful.
“A threat was made and we didn’t think it was appropriate, so I have to be very careful. So I do that on the basis of safety for our people. A threat was made by a former president of Russia and we’re going to protect our people.”
The spat between Mr Trump and Mr Medvedev came after the US president warned Russia on Tuesday it had “10 days from today” to agree to a ceasefire in Ukraine or face tariffs, along with its oil buyers.
Moscow has shown no sign that it will agree to Mr Trump’s demands.
Trump’s move appears to signal a significant deterioration in relationship with Putin
Normally it’s Moscow rattling the nuclear sabres, but this time it’s Washington in what marks a dramatic escalation in Donald Trump’s war of words with the former Russian president Dmitry Medvedev.
More importantly, it appears to signal a significant deterioration in his relationship with Vladimir Putin.
The US president’s patience with the Kremlin was already at its thinnest earlier this week, when he shrank his deadline for progress towards a peace deal from 50 days to 10.
But Russia’s lack of outward concern with this stricter ultimatum – which has swung from dismissive to (in Medvedev’s case) insulting – seems to have flicked a switch.
For this is the first time Trump’s pressure on Moscow has amounted to anything more than words.
We don’t know where the subs are, or how far they had to move to get closer to Russia, but it’s an act that sits several rungs higher than the usual verbal threats to impose sanctions.
How will Russia respond? I’m not sure Vladimir Putin has ever caved to an ultimatum and I doubt he’ll start now.
But I don’t think he’ll want the situation to deteriorate further. So I suspect he’ll make another offer to the US, that’s dressed up as a concession, but in reality may prove to be anything but.
It’s a tactic that’s worked before, but the stakes have suddenly got higher.
On Thursday, Mr Medvedev reminded Mr Trump that Russia possessed a Soviet-era automated nuclear retaliatory system – or “dead hand”.
Mr Medvedev, a close ally of Russian President Vladimir Putin, was referring to a secretive semi-automated Soviet command system designed to launch Russia’s missiles if its leadership was taken out in a decapitating strike.
He made the remarks after Mr Trump told him to “watch his words” after Mr Medvedev said the US president’s threat of hitting Russia and its oil buyers with punitive tariffs was “a game of ultimatums” and added that “each new ultimatum is a threat and a step towards war” between Russia and the US.

Mr Medvedev served as Russia’s president from 2008 and 2012, when Mr Putin was barred from seeking a third consecutive term, but then stepped aside to let him run again.
As deputy chair of Russia’s Security Council, he has become known for his provocative and inflammatory statements since Moscow invaded Ukraine in 2022.
Donald Trump has said “nobody has asked” him to pardon Ghislaine Maxwell, but insisted he has “the right to do it” as US president.
Jeffrey Epstein’s former girlfriend is currently serving a 20-year sentence after being convicted of helping the paedophile financier traffic and sexually abuse underage girls in 2021.
Prosecutors have said Epstein’s sex crimes could not have been done without Maxwell, but her lawyers have maintained that she was wrongly prosecuted and denied a fair trial, and have floated the idea of a pardon from Mr Trump.
Last week, they asked the US Supreme Court to take up her case.
When pressed on the possibility of pardoning Maxwell, Mr Trump told reporters: “I’m allowed to do it, but nobody’s asked me to do it.”
He continued: “I know nothing about it. I don’t know anything about the case, but I know I have the right to do it. I have the right to give pardons, I’ve given pardons to people before, but nobody’s even asked me to do it.”
Mr Trump also said he would not pardon Sean “Diddy” Combs, who was convicted in July on two charges of transportation to engage in prostitution.

Trump ‘never visited Espstein island’
His comments came shortly after the federal Bureau of Prisons (BOP) said Maxwell has been moved to a minimum-security prison camp in Texas.
She was being held at a low-security prison in Tallahassee, Florida, that housed men and women, but has now been transferred to a prison camp in Bryan, Texas.
When asked why Maxwell was transferred, BOP spokesperson Donald Murphy said he could not comment on the specifics, but that the BOP determines where inmates are sent based on such factors as “the level of security and supervision the inmate requires”.
Maxwell’s lawyer confirmed the move but also declined to discuss the specific reasons for it.
The Texas camp houses solely female prisoners, the majority of whom are serving time for nonviolent offences and white-collar crimes, Sky’s US partner NBC News reports.

Minimum-security federal prison camps house inmates considered to be the lowest security risk and some facilities do not even have fences.
A senior administration official told NBC: “Any false assertion this individual was given preferential treatment is absurd.
“Prisoners are routinely moved in some instances due to significant safety and danger concerns.”
Maxwell has received renewed attention in recent weeks, after the US Justice Department said it would not be releasing the so-called ‘Epstein files’.
The department said a review of the Epstein case had found “no incriminating ‘client list'” and “no credible evidence” the jailed financier – who killed himself in prison in 2019 – had blackmailed famous men.
Officials from the Trump administration have since tried to cast themselves as promoting transparency in the case.
Last month, they lodged a request to unseal grand jury transcripts – which was denied – and Maxwell was last week interviewed by Deputy Attorney General Todd Blanche.
Epstein survivor’s family criticises move
Maxwell’s move to a lower security facility has been criticised by the family of Epstein abuse survivor Virginia Giuffre, who died in April, and accusers Annie and Maria Farmer.
They said in a statement: “It is with horror and outrage that we object to the preferential treatment convicted sex trafficker Ghislaine Maxwell has received.
“Ghislaine Maxwell is a sexual predator who physically assaulted minor children on multiple occasions, and she should never be shown any leniency.
“Yet, without any notification to the Maxwell victims, the government overnight has moved Maxwell to a minimum security luxury prison in Texas.”
The statement concluded: “This move smacks of a cover up. The victims deserve better.”
A jury has ruled that Tesla is partly to blame for the death of a young woman who was hit by an electric car on Autopilot.
Naibel Benavides was stargazing at the time of the collision, which sent her flying 22m (75ft) through the air in Florida.
Her boyfriend was seriously injured in the 2019 incident, while her body was discovered in a wooded area.

The company has now been ordered to pay $243m (£183m) in damages to Ms Benavides’ family, and to her partner Dillon Angulo.
Jurors concluded that not all of the blame could be put on a reckless driver who admitted he was distracted by his phone before he hit the young couple.
The motorist, George McGee, reached a separate settlement with the victims’ families in an earlier case.
Brett Schreiber, who represented the victims, said: “Tesla designed Autopilot only for controlled-access highways yet deliberately chose not to restrict drivers from using it elsewhere, alongside Elon Musk telling the world Autopilot drove better than humans.

Tesla bruised by Musk-Trump fallout
Tesla – and Elon Musk – have said it will appeal the verdict, labelling it “wrong” and a setback for automotive safety.
The verdict would also work to “jeopardise Tesla’s and the entire industry’s efforts to develop and implement life-saving technology”, the company warmed.
Tesla had claimed Mr McGee was solely to blame for the fatal crash because he had reached down to pick up a dropped mobile phone as his Model S sped through an intersection in Key Largo, Florida, at about 62mph.
Mr McGee allegedly did not receive alerts as he ran a stop sign and a red light – and the plaintiffs’ lawyer argued that the driver’s assistance should have warned the driver and braked before the collision.
The collision sent Ms Benavides Leon flying 22m (75ft) through the air, with her body later being discovered in a wooded area, while Mr Angulo suffered serious injuries.
“To be clear, no car in 2019, and none today, would have prevented this crash,” Tesla said. “This was never about Autopilot; it was a fiction concocted by plaintiffs’ lawyers blaming the car when the driver – from day one – admitted and accepted responsibility.”
Lawyers for the plaintiffs also alleged that Tesla either hid or lost key evidence, including data and video recorded seconds before the collision.
They showed the court that the company had the evidence all along, despite repeated denials, after hiring a forensic data expert who dug it up.
After being shown the evidence, Tesla said it made a mistake and honestly hadn’t thought it was there.

Past cases against Tesla were dismissed or settled, so the verdict in this case could encourage more legal action.
Miguel Custodio, a car crash lawyer not involved in this trial, added: “This will open the floodgates. It will embolden a lot of people to come to court.”
The verdict comes as Mr Musk plans to roll out a driverless taxi service, hoping to convince people his vehicles are safe enough to drive on their own.
Improvements to the company’s driver assistance and partial self-driving features have been made in recent years – but in 2023, 2.3 million Tesla vehicles were recalled amid fears Autopilot was failing to sufficiently alert drivers not paying attention to the road.
