More than a dozen new tents have popped up at two locations along the U.S. border with Mexico. These are temporary courtrooms for migrants who are claiming asylum. They offer a glimpse into how the Trump administration’s unprecedented crackdown on immigration is playing out with judges deciding the fate of hundreds of asylum seekers via video, and in makeshift facilities. We pinpointed their locations and satellite imagery and tracked their expansion over a month. We can see them here, along the border in Laredo, Tex. There are several long tents, subdivided into courts, where 420 asylum hearings are planned each day. And in Brownsville, Tex., another set of tent courthouses. This one, for more than 700 cases a day. Judges will handle cases via video. A top immigration official spoke recently, praising the technology. “Spectacular video-conferencing facility, the mechanics of that will be used for hearings.” But some advocates have said that this will worsen already limited due process for asylum seekers. And a 2017 Justice Department study also raised additional concerns about video and the difficulty for judges to analyze eye contact, nonverbal forms of communication and body language. These courtroom tents are part of the so-called Remain in Mexico policy, which is formally known as the Migrant Protection Protocols. It was implemented in January and aimed at limiting the number of asylum seekers arriving in the U.S. “They will have to wait for approval to come into the United States: If they are granted asylum by a U.S. judge, they will be welcomed into America, if they are not, they will be removed to their home countries.” Typically, people seeking asylum were allowed to remain in the United States while their cases went through courts around the country, due to the danger they would face at home. Putting these tent courts along the border allows the U.S. to send asylum seekers to Mexico until it’s time for their hearings. But this could also put people in harm’s way. The location of these tent courts means some asylum seekers will be forced to await their trials in some of the most dangerous cities along the border in Mexico. Brownsville and Laredo border the Mexican state of Tamaulipas, where the U.S. State Department has issued a travel advisory to the same degree as for Syria and Afghanistan. American citizens are told not to travel here due to crime and kidnapping, and human rights groups have documented cases of rape, abduction and murder of migrants. Meanwhile, U.S. immigration authorities are considering additional locations for tent courts. But by forcing asylum seekers to wait in high-risk areas, some migrants may never be able to return for their day in court.
