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.
Israel has approved a plan to capture all of the Gaza Strip and remain there for an unspecified length of time, Israeli officials say.
According to Reuters, the plan includes distributing aid, though supplies will not be let in yet.
The Israeli official told the agency that the newly approved offensive plan would move Gaza’s civilian population southward and keep humanitarian aid from falling into Hamas’s hands.
On Sunday, the United Nations rejected what it said was a new plan for aid to be distributed in what it described as Israeli hubs.
Israeli cabinet ministers approved plans for the new offensive on Monday morning, hours after it was announced that tens of thousands of reserve soldiers are being called up.
Prime Minister Benjamin Netanyahu has so far failed to achieve his goal of destroying Hamas or returning all the hostages, despite more than a year of brutal war in Gaza.

Officials say the plan will help with these war aims but it would also push hundreds of thousands of Palestinians to southern Gaza, exacerbating an already dire humanitarian crisis.

They said the plan included the “capturing of the strip and the holding of territories”.
It would also try to prevent Hamas from distributing humanitarian aid, which Israel says strengthens the group’s rule in Gaza.
The UN rejected the plan, saying it would leave large parts of the population, including the most vulnerable, without supplies.
It said it “appears designed to reinforce control over life-sustaining items as a pressure tactic – as part of a military strategy”.

More than 52,000 Palestinians have been killed since the IDF launched its ground offensive in the densely-populated territory, according to the Hamas-run health ministry.
It followed the deadly Hamas attacks on Israel, which killed 1,200 people and saw around 250 people taken hostage.
A fragile ceasefire that saw a pause in the fighting and the exchange of Israeli hostages and Palestinian prisoners collapsed earlier this year.
Yemen’s Houthi rebel group has said 15 people have been injured in “US-British” airstrikes in and around the capital Sanaa.
Most of those hurt were from the Shuub district, near the centre of the city, a statement from the health ministry said.
Another person was injured on the main airport road, the statement added.
It comes after Israeli Prime Minister Benjamin Netanyahu vowed to retaliate against the Houthis and their Iranian “masters” following a missile attack by the group on Israel’s main international airport on Sunday morning.
It remains unclear whether the UK took part in the latest strikes and any role it may have played.
On 29 April, UK forces, the British government said, took part in a joint strike on “a Houthi military target in Yemen”.
“Careful intelligence analysis identified a cluster of buildings, used by the Houthis to manufacture drones of the type used to attack ships in the Red Sea and Gulf of Aden, located some fifteen miles south of Sanaa,” the British Ministry of Defence said in a previous statement.

On Sunday, the militant group fired a missile at the Ben Gurion Airport, sparking panic among passengers in the terminal building.
The missile impact left a plume of smoke and briefly caused flights to be halted.
Four people were said to be injured, according to the country’s paramedic service.
This breaking news story is being updated and more details will be published shortly.
Israeli Prime Minister Benjamin Netanyahu has vowed to retaliate against the Houthis and their Iranian “masters” after the group launched a missile attack on the country’s main international airport.
A missile fired by the group from Yemen landed near Ben Gurion Airport, causing panic among passengers in the terminal building.
“Attacks by the Houthis emanate from Iran,” Mr Netanyahu wrote on X. “Israel will respond to the Houthi attack against our main airport AND, at a time and place of our choosing, to their Iranian terror masters.”

The missile impact left a plume of smoke and briefly halted flights and commuter traffic at the airport. Some international carriers have cancelled flights to and from Tel Aviv for several days.
Four people were lightly wounded, paramedic service Magen David Adom said.
Air raid sirens went off across Israel and footage showed passengers yelling and rushing for cover.
The attack came hours before senior Israeli cabinet ministers were set to vote on whether to intensify the country’s military operations in the Gaza Strip, and as the army began calling up thousands of reserves in anticipation of a wider operation in the enclave.

Houthi military spokesperson Brigadier General Yahya Saree said the group fired a hypersonic ballistic missile at the airport.
Iran’s defence minister later told a state TV broadcaster that if the country was attacked by the US or Israel, it would target their bases, interests and forces where necessary.
Israel’s military said several attempts to intercept the missile were unsuccessful.
Air, road and rail traffic were halted after the attack, police said, though it resumed around an hour later.

Yemen’s Houthis have been firing missiles at Israel since its war with Hamas in Gaza began on 7 October 2023, and while most have been intercepted, some have penetrated the country’s missile defence systems and caused damage.
Israel has previously struck the group in Yemen in retaliation and the US and UK have also launched strikes after the Houthis began attacking international shipping, saying it was in solidarity with Palestinians over Israel’s war with Hamas.
