Mothers carrying their children smile, give me a thumbs up, and then point to a riverbank fifty 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.
All the latest US election updates
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.
Marlen Cabrera says making it the US is the only option she and her family have
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.”
A US border agent checks migrant paperwork
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.

Thousands of people gathered in various cities across the US as protests against Donald Trump and Elon Musk took place in all 50 states on Saturday.
Around 1,200 demonstrations were planned in locations including Washington DC, New York City and West Palm Beach, Florida – just miles away from where the US president has this weekend played golf.
The “Hands Off!” protests were against the Trump administration’s handling of government downsizing, human rights and the economy, among other issues.
In Washington DC, protesters streamed on the grass in front of the Washington Monument, where one person carried a banner which read: “Make democracy great again.”

Another protester took aim at Mr Trump‘s handling of Russia and Ukraine, with a placard that read: “Stop Putin’s puppets from destroying America.”
Tesla boss Mr Musk also featured on many signs due to his role in controversial government cuts as head of the newly created Department of Government Efficiency (DOGE).

Terry Klein, a retired biomedical scientist, said she drove to the rally to protest Mr Trump’s policies on “everything from immigration to the DOGE stuff to the tariffs this week, to education”.
“I mean, our whole country is under attack, all of our institutions, all the things that make America what it is,” she added.

Some at the various protests carried Ukrainian flags, while others sported rainbow attire and waved rainbow flags in support of the LGBTQ+ community.
Other protesters wore Palestinian keffiyeh scarves and carried “Free Palestine” signs.
Thousands marched in New York City’s midtown Manhattan and in Boston, Massachusetts, while hundreds gathered in the sunshine outside the Utah State Capitol building in Salt Lake City, and in the rain outside the Statehouse in Columbus, Ohio.

Mr Trump – who shook financial markets with his tariffs announcement this week – spent the day in Florida, playing a round of golf before returning to his Mar-a-Lago residence.

Some four miles from Mar-a-Lago, more than 400 people gathered – and drivers honked their horns in support of protesters who held up signs including one which read: “Markets tank, Trump golfs.”
The White House has said Mr Trump plans to go golfing again on Sunday.
