TIJUANA, Mexico -- Slowly but steadily, caravan migrants who trekked across Mexico are pleading their cases to US authorities on why they should be granted asylum.
As of Wednesday afternoon, 53 migrants had begun the process -- officials said they expect to have admitted 74 asylum-seekers to border facilities by the end of the day.
Those who have made their plea are now in a detention center known as the "hielera," or "cooler." They could be held for days, or even a week, as asylum officers question them and assess them for "credible fear."
The initial eight migrants to begin the process were selected by their peers to apply for asylum first. They include Gabriela Hernandez, a pregnant mother of two who fled Honduras. She and her two sons, ages 6 and 2, have battled hunger, exhaustion and chronic illness throughout the journey.
One organizer said the caravan would remain at the immigration processing center until "every last one is admitted into the United States."
What these migrants are fleeing from
Hernandez left her husband after suffering domestic abuse, but then gang members found her one day, demanding to know where her ex was. They gave her 12 hours to give him up or said they would kill her 6-year-old.
She left that night, with her sons.
Her plan was to present herself to US officials to claim asylum given the danger to her life and her children in Honduras. She just doesn't have the energy to think what would be next if she is not granted asylum.
"I don't know what I'm going to do," she said. "I cannot go back to my country."
Tesla Rich, 19, and her 9-month-old daughter, Valentina, are also in the first group of eight selected to start their asylum claims.
She's leaving the rampant violence in Honduras -- her uncle and sister were killed in recent years. Rich is looking for work, something she said is nearly impossible to find in her country.
Her dream, if she gets to stay in the United States, is to bring her other daughter, whom she had to leave behind.
Catherine Enamorado fled Honduras with her 12-month-old daughter, Ashly, after MS-13 gang members tried to recruit Catherine's boyfriend, who is Ashly's father.
He said no, and gang members showed up later at her house, saying they would rape her and the baby if she didn't convince him to join, Catherine said.
Catherine said she left behind her 4- and 5-year-old sons with her father.
Sarae Carrillo, 24, feared gang violence in El Salvador, so she left with her daughter, Daryelen, 2.
They have extended family in the United States they hope to see soon.
"We walked a lot," Sarae said. "We got on the train called 'La Bestia.' We're tired of waiting, but we have nowhere else to go."
Trump says no to these migrants
President Donald Trump has tweeted that these migrants shouldn't be allowed into the country. Vice President Mike Pence called the caravan "a deliberate attempt to undermine the laws of this country and the sovereignty of the United States."
But migrants from this caravan are at a port of entry and asking for asylum. And under international law, the United States and other countries must consider asylum claims.
Trump has decried the practice of letting immigrants with pending cases leave detention in some cases -- and vowed his administration will put an end to the policy, which he calls "catch and release."
But if history is an indicator, the odds of these migrants getting asylum are slim.
More than 75% of applicants from Honduras, Guatemala and El Salvador between 2011 and 2016 were rejected, according to Syracuse University's Transactional Records Access Clearinghouse.
But parents in this caravan said they're willing to take their chances.
"I don't have an option," one 38-year-old woman told CNN. "If I stay in El Salvador, I'm going to be killed."
