“I left my country on 26 August 2014,” explains Mr Janvier, his three-year-old son absentmindedly playing with a toy car on the restaurant floor.

Having spent several years in Brazil, he moved to Chile, met his wife and they had a child. But as they could not move beyond the lowest social rung in South America, they decided the time was right to attempt to reach the US.

“We have been through eleven different countries to get here. Bolivia, Peru, Ecuador…” Mr Janvier begins to name them in order, describing an extraordinary journey on foot and by bus, that traverses the Andes and the Amazonian Basin.

It was a deeply harrowing trip too.

As he took his young family across the Darien Gap, seven days through the dense jungle between Colombia and Panama, Mr Janvier says he saw the dead bodies of other Haitian and Cuban migrants.

He describes being robbed of what little he had by “bandits”, most likely members of violent drug and people-smuggling gangs which operate in the region. He said some of the women were raped, although his wife managed to hide with the child when the gang appeared.

Migrant rights groups estimate that in Mexico alone as many as 80% of migrants have been victimised, extorted or abused on their journey, many of them by the police and the immigration authorities.

Were it not enough, along the way Mr Janvier received some awful news from home. When a 7.2 magnitude earthquake struck Haiti in August, the worst affected city was Les Cayes – his hometown.

His mother was among the 2,200 people who died in the quake, trapped under the rubble of the family home. His father lost a leg. Mr Janvier shows me photographs of the destroyed house on his phone, and begins to fight back tears.

“I had to keep going. My father has no-one now, the only person who can send him money is my brother [in the US],” he says. “And I need to help too.”

So, the biggest fear for Mr Janvier, and the other Haitians at the restaurant’s plastic tables, is not dying in the desert but deportation.

Haiti is at its lowest ebb in years. The president was assassinated in July, gang violence is spiralling, and the country is grappling with economic ruin and the effects of climate change.

“Haiti is like hell for me now,” he says with seriousness. “There is nothing for me there. Nothing. If they’re going to send me back, they may as well just kill me. Just end it all.”

It is not the only time Mr Janvier refers to his journey as a matter of life and death. It is something echoed by Kelly Overton, the executive director of Border Kindness, which provides education, health and legal services to migrants in Mexicali.

“There does seem to be a level of desperation from the families from Haiti right now,” he says. “They say there’s no option to go back, no safe place to go back to, no possibility of a life that’s worth living.”
