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.
It was the first time a US president had been convicted of or charged with a criminal offence.
Trump had tried to cover up “hush money” payments to a porn star in the days before the 2016 election.
When Stormy Daniels‘ claimsof a sexual liaison threatened to upend his presidential campaign, Trump directed his lawyer to pay $130,000 (£102,000) to keep her quiet.
The payment buried the story and he later won the presidency.
Trump denied the charges and said the case was politically motivated. He also denied the sexual encounter took place.
New York State Supreme Court Justice Juan Merchan today delayed the sentencing, which had been due to take place on Tuesday.

The office of district attorney Alvin Bragg had asked the judge to postpone all proceedings until Trump finishes his four-year presidency, which starts on 20 January.
Trump’s lawyers say the case should be dismissed because it will create “unconstitutional impediments” to his ability to govern.
Responding to Friday’s decision, a Trump campaign spokesman said: “The American People have issued a mandate to return him to office and dispose of all remnants of the Witch Hunt cases.”
The judge set a 2 December deadline for Trump’s lawyers to file their motion, while prosecutors have until 9 December to respond.
He did not set a new date for sentencing or indicate when he would rule on any motion to throw out the case.
Even before Trump’s win in this month’s election, experts said a jail term was unlikely and a fine or probation more probable.
But his resounding victory over Kamala Harris made the prospect of time behind bars or probation even less likely.
Trump, 78, was also charged last year in three other cases.
One involved him keeping classified documents after he left office and the other two centre on alleged efforts to overturn his 2020 election loss.
A Florida judge dismissed the documents case in July, the Georgia election case is in limbo, and the Justice Department is expected to wind down the federal election case as it has a policy of not prosecuting a sitting president.
Trump last week nominated his lawyers in the hush money case, Todd Blanche and Emil Bove, for senior roles in the Justice department.
When he re-enters the White House, Trump will also have the power to shut down the Georgia and New York cases.
Donald Trump has pledged for years to surround himself with ultra-loyalists who can mould his government to his vision without barriers.
That’s precisely why he picked Matt Gaetz. Now he’s out, Pam Bondi is in and she’s equally loyal.
Gaetz was uniquely unpopular on Capitol Hill but ultra-MAGA and ultra-loyal to the president-elect.
He was chosen by the president-elect to do his bidding inside the Justice Department as attorney general.
Critics called his pick “a red alert moment for democracy” and the man a “gonzo agent of chaos” – language that would surely only affirm Trump’s decision in his own proudly disruptive mind.
If it wasn’t for the fact that the president-elect is himself a convicted felon, and a man found liable in a civil court of his own sexual offences, the prospect of Gaetz, with all his baggage, making it through the nomination process would have seemed remote.
But Donald Trump’s return to the White House suggested anything is possible.
And so, beyond his loyalty, Gaetz was Trump’s test for his foot soldiers on Capitol Hill. How loyal were they? Would they wave through anyone he appointed?
It turns out that Gaetz, and the storm around his private life, was too much for a proportion of them.

At least five Senate Republicans were flatly against Matt Gaetz’s confirmation. We understand that they communicated to other senators and those close to Trump that they were unlikely to be swayed.
They included the Republican old guard like Senator Mitch McConnell.
Beyond the hard “no” senators, there were between 20 and 30 other Republicans who were very uncomfortable about having to vote for Gaetz on the Senate floor.

Trump pick Matt Gaetz withdraws
The key question is whether Gaetz was Trump’s intentional wild card crazy choice that he knew, deep down, would probably never fly.
Was Gaetz the candidate he had accepted would be vetoed by senators – who would then feel compelled to wave the rest of his nominees through?
Will Pete Hegseth’s alleged sexual impropriety concern them as they consider the suitability of the former Fox News host and army major to run the Department of Defence?
What about Tulsi Gabbard, the candidate Russian state TV calls ‘our girl’, and the appropriateness of her running America’s intelligence agencies?
These are all appointments that the politicians on Capitol Hill must consider and confirm in the weeks ahead.
We don’t yet know who Trump will choose to direct the FBI.
There are some names being floated which will make the establishment of Washington shudder but then that’s precisely why Trump was elected. He is the disrupter. He said so at every rally, on repeat.
He was quick to pivot to another name to replace Gaetz.
Bondi is the former attorney general of Florida. Professionally she is in a different league to Gaetz. She’s been a tough prosecutor, with a no-nonsense reputation.
She is also among the most loyal of loyalists. Her attachment to Trump stretches way back.
I first came across her in Philadelphia in November 2020 when she was among Trump surrogates claiming the election back then had been stolen from them by Joe Bidenand the Democrats.
She was a key proponent of the false claims the election had been rigged and Trump was the rightful winner.
The court cases concluding that was all nonsense didn’t seem to convince her.
Now she is poised to head up the Department of Justice as the country’s top law enforcement official.
Within hours of taking office, president-elect Donald Trump plans to begin rolling out policies including large-scale deportations, according to his transition team.
Sky News partner network NBC News has spoken with more than half a dozen people familiar with the executive orders that his team plans to enact.
One campaign official said changes are expected at a pace that is “like nothing you’ve seen in history”, to signal a dramatic break from President Joe Biden’s administration.
Mr Trump is preparing on day one to overturn specific policies put in place by Mr Biden. Among the measures, reported by sources close to the transition team, are:
• The speedy and large-scale deportations of illegal immigrants
• Ending travel reimbursement for military members seeking abortion care
• Restricting transgender service members’ access to gender-affirming care

But much of the first day is likely to focus on stopping illegal immigration – the centrepiece of Trump’s candidacy. He is expected to sign up to five executive orders aimed at dealing with that issue alone after he is sworn in on 20 January.
“There will without question be a lot of movement quickly, likely day one, on the immigration front,” a top Trump ally said.

“There will be a push to make a huge early show and assert himself to show his campaign promises were not hollow.”

Donald Trump ally Matt Gaetz has withdrawn his name from consideration to be the next US attorney general.
But Mr Trump’s campaign pledges also could be difficult to implement.
Deporting people on the scale he wants will be a logistical challenge that could take years. Questions also remain about promised tax cuts.
Meanwhile, his pledge to end the war between Russia and Ukraine in just 24 hours would be near impossible.
Even so, advisers based at Mr Trump’s Mar-a-Lago resort or at nearby offices in West Palm Beach, Florida, are reportedly strategising about ending the wars in Ukraine and the Middle East.
Following his decisive victory on 5 November, the president-elect has moved swiftly to build a cabinet and senior White House team.
As of Thursday, he had selected more than 30 people for senior positions in his administration, compared with just three at a similar point in his 2016 transition.
Stephen Moore, a senior economic adviser in Mr Trump’s campaign, told NBC News: “The thing to realise is Trump is no dummy.
“He knows he’s got two to three years at most to get anything done. And then he becomes a lame duck and we start talking about [the presidential election in] 2028.”
