Abel Oset was seized with panic. After an 11-country odyssey that began when he and his namesake son fled Cuba, and included a moment on U.S. soil, he was crossing back into America.
But he wasn't sure he'd be able to stay.
The two were going to plead their case in a court set up inside a tent in Laredo, Texas, beamed via video conference to a judge in another city — the latest attempt to clear a massive backlog of asylum cases.

They were among more than 100 migrants on Tuesday's docket — though only 38 had arrived. So much depended on this hearing; Oset dreaded the very real possibility that he and his 22-year-old son would be sent back over the international bridge, back to Nuevo Laredo, in Tamaulipas, and its cartels and violence.
Awaiting his hearing in the pre-dawn hours, Oset lay on the floor of a migration building. He spoke of the criminals who stalk the bridge, picking off migrants. He and his son were targeted by kidnappers twice but had no money and were turned loose with warnings not to return.
"Those who arrive are being taken, one by one," he said.
Some migrants awaiting hearings arrived at the bridge before sunset Monday from Monterrey, hundreds of miles from the border. Others left city hostels early to avoid moving at night.
At least 42,000 migrants have been forced back into Mexico after crossing the border, according to the U.S. government. Many of them say they fled violence or threats in their home countries and hope to get asylum.
The Department of Homeland Security has said it planned to spend $155 million to build and operate the tent courts but expects the costs to be less. But critics have denounced the proceedings because they are closed to the public and difficult for attorneys to access.
President Donald Trump's top lieutenants on immigration and border enforcement toured the tent complex in Laredo on Tuesday, defending the "remain in Mexico" policy. The complex includes several rooms where court hearings are held, people wait and children can read storybooks in Spanish.
During the tour, there were 15 immigrants in a processing room and two dozen in a room where migrants await a decision on their case. With the temperature outside approaching 100 degrees, air conditioning units blasted cold air through the tents, creating a din that makes it difficult to hear.
Many of the migrants making court appearances complain of the dangers they face as they are forced to wait in crime-ridden Nuevo Laredo. The U.S. government has warned Americans not to travel to the area, citing safety concerns.
Acting Homeland Security Secretary Kevin McAleenan defended the "remain in Mexico" policy, calling it a reasonable alternative to separating and detaining families in the U.S.
"You are seeing a team effort across four agencies and two departments to run an expeditious lawful process so that families are staying together during their process so that they can wait in a non-detained setting for their hearing," he said.
"We're getting more integrity into the system to deter those who don't have valid claims from making the journey," McAleenan added.
For Trump, curbing immigration remains his signature issue, and his administration also is dealing with a massive increase in migrants, mostly Central American families, that has strained the immigration system. A major aim of these programs is to deter people from coming to the southern border.
Mexico has cracked down on migrants coming to its southern border, and the U.S. is working on diplomatic agreements with other Central American countries.
The U.S. Supreme Court last week made it vastly more difficult for people to win asylum, allowing the new rules into effect during litigation challenging them. The rules bar anyone who passed through another country from claiming asylum, though some other protections may still be available.
Oset hoped that because he came before July 16, when the regulations came into effect, he would pass. But he also had to convince the judge he was afraid not only to return to his home country, but to Mexico.
"I fall into the old law, and I think that can help us," he said.
He got lucky; he and his son were allowed into the U.S., but 10 other adults and three children in the group were returned.
The two arrived at the U.S.-Mexico border in April. They fled Cuba when a neighbor reported him to state security for watching a documentary about the Castro family's possessions, and he was beaten, Oset said. He was returned to Mexico to wait for his asylum hearing.
Immigrants and advocates trying to help in Mexican border cities have reported families sleeping in overcrowded shelters, boarding houses or outdoor camps. Many have been bused south by Mexico to cities considered safer, though there was no guarantee that they would be able to return.
Meanwhile, the U.S. Border Patrol's Rio Grande Valley chief recently testified that the agency was sending more than 1,000 migrants a week to Tamaulipas.
Margarita Arredondo, pastor of an evangelistic church, converted her home into a shelter and helps migrants make their hearings.
"You have to give them protection because Mexico is not a safe country, that is very clear," she said.
According to data from Mexican Foreign Minister Marcelo Ebrard, nearly half of those who were sent to Mexico from the U.S. returned to their homes.
"They don't want us anywhere — Mexicans reject us, too," said a 29-year-old Honduran woman who spoke only on condition of anonymity because she was afraid.
She says she has just learned about the murder of a friend in Intibucá, where she fled, leaving two children behind with her mother because the gangs threatened her.
She has no documents, common among migrants who flee their homes quickly out of fear.
Her eyes fill with tears when asked what she will do if she is returned to Nuevo Laredo.
"God will see," she said.
