CIUDAD JUAREZ, MEXICO — On Wednesday in this border city, Carmen, a Cuban woman who’s been stuck here since May, fought to contain her rage and desperation.

“I feel like an idiot,” she said. “I don’t know what’s going to happen now. Do you know what’s going to happen?”

About the same time — and more than 900 miles away in the Mexican city of Matamoros — Jorge Luis Gutierrez, also from Cuba, was reeling from what he said was a trap laid for asylum seekers by the Mexican and American governments.

“They’re trying to deceive us,” he said just steps away from the international bridge between the U.S. and Mexico.

On Monday, the Trump administration announced a new policy that would disqualify most asylum seekers from receiving protections in the United States if they didn’t first apply for asylum in another country.

Now, tens of thousands of migrants who have been waiting for months in Mexican border cities are struggling to understand what the policy means for them, even though they’ve followed the rules and have waited to enter the United States legally at a port of entry instead of unlawfully crossing the Rio Grande.

On Tuesday, the American Civil Liberties Union, the Southern Poverty Law Center and the Center for Constitutional Rights in the Northern District of California filed a lawsuit to halt the new policy. But for the migrants in Mexico, that provided little solace.

“Maybe I should have tried to enter illegally,” Carmen said, her voice rising. “Maybe I would have been with my son [in Florida] already.”

Carmen and Gutierrez have both been waiting to apply for asylum in Mexico for about two months after the United States implemented its “metering” policy that limits the number of immigrants that are allowed to apply on a given day. Several of the Cubans waiting in Matamoros said there were 2,500 on the list there. But no one has been taken to cross the bridge in two days, Jorge Luis claimed.

In Ciudad Juárez, there are about 5,000 people on the list, although it’s unclear how many have given up and returned to their home countries, said Enrique Valenzula, the director of Ciudad Juárez’s Centro de Atención a Migrantes, a migrant transition facility operated by the Chihuahua state government. The number could be closer to 3,500.

On Tuesday afternoon, only five migrants were allowed to cross, and not one number was called Wednesday morning. On other days, dozens have been allowed to enter. The latest slowdown had Carmen and others on edge.

“They haven’t given us any information,” she said.

Valenzuela said the slowdown isn’t unheard of but conceded it’s adding to an already stressful situation.

“They’re worried, above all, because they’ve waited for three months. They’ve been waiting for the moment they’re called and are able to cross in an orderly fashion,” he said. “And now, these people are saying they’ve waited and there are people that crossed another way before this [policy] and they’re already living in the United States.”

Some of the migrants waiting in Mexico have suddenly opted to cross the Rio Grande instead of waiting for their numbers to be called.

Gutierrez said about a dozen took that chance Wednesday, including “kids and pregnant women” he said. The group consisted of Cubans, Venezuelans and Hondurans who swam while others went on inner tubes as the women held on, he said.

Since last month, however, the Mexican military and federal police have been dispatched to the northern border to prevent people from crossing the river. One of the soldiers told the Tribune they were sent to the banks of the Rio Grande after reports that a dozen migrants crossed illegally Wednesday morning. He said they were under orders to interdict migrants attempting to cross, then call migration authorities to the scene.
