Early next week, according to a D.H.S. official, the Trump Administration is expected to announce a major immigration deal, known as a safe-third-country agreement, with Guatemala. For weeks, there have been reports that negotiations were under way between the two countries, but, until now, none of the details were official. According to a draft of the agreement obtained by The New Yorker, asylum seekers from any country who either show up at U.S. ports of entry or are apprehended while crossing between ports of entry could be sent to seek asylum in Guatemala instead. During the past year, tens of thousands of migrants, the vast majority of them from Central America, have arrived at the U.S. border seeking asylum each month. By law, the U.S. must give them a chance to bring their claims before authorities, even though there’s currently a backlog in the immigration courts of roughly a million cases. The Trump Administration has tried a number of measures to prevent asylum seekers from entering the country—from “metering” at ports of entry to forcing people to wait in Mexico—but, in every case, international obligations held that the U.S. would eventually have to hear their asylum claims. Under this new arrangement, most of these migrants will no longer have a chance to make an asylum claim in the U.S. at all. “We’re talking about something much bigger than what the term ‘safe third country’ implies,” someone with knowledge of the deal told me. “We’re talking about a kind of transfer agreement where the U.S. can send any asylum seekers, not just Central Americans, to Guatemala.”

From the start of the Trump Presidency, Administration officials have been fixated on a safe-third-country policy with Mexico—a similar accord already exists with Canada—since it would allow the U.S. government to shift the burden of handling asylum claims farther south. The principle was that migrants wouldn’t have to apply for asylum in the U.S. because they could do so elsewhere along the way. But immigrants-rights advocates and policy experts pointed out that Mexico’s legal system could not credibly take on that responsibility. “If you’re going to pursue a safe-third-country agreement, you have to be able to say ‘safe’ with a straight face,” Doris Meissner, a former commissioner of the Immigration and Naturalization Service, told me. Until very recently, the prospect of such an agreement—not just with Mexico but with any other country in Central America—seemed far-fetched. Yet last month, under the threat of steep tariffs on Mexican goods, Trump strong-armed the Mexican government into considering it. Even so, according to a former Mexican official, the government of Andrés Manuel López Obrador is stalling. “They are trying to fight this,” the former official said. What’s so striking about the agreement with Guatemala, however, is that it goes even further than the terms the U.S. sought in its dealings with Mexico. “This is a whole new level,” the person with knowledge of the agreement told me. “In my read, it looks like even those who have never set foot in Guatemala can potentially be sent there.”

At this point, there are still more questions than answers about what the agreement with Guatemala will mean in practice. A lot will still have to happen before it goes into force, and the terms aren’t final. The draft of the agreement doesn’t provide much clarity on how it will be implemented—another person with knowledge of the agreement said, “This reads like it was drafted by someone’s intern”—but it does offer an exemption for Guatemalan migrants, which might be why the government of Jimmy Morales, a U.S. ally, seems willing to sign on. Guatemala is currently in the midst of Presidential elections; next month, the country will hold a runoff between two candidates, and the current front-runner has been opposed to this type of deal. The Morales government, however, still has six months left in office. A U.N.-backed anti-corruption body called the CICIG, which for years was funded by the U.S. and admired throughout the region, is being dismantled by Morales, whose own family has fallen under investigation for graft and financial improprieties. Signing an immigration deal “would get the Guatemalan government in the U.S.’s good graces,” Stephen McFarland, a former U.S. Ambassador to Guatemala, told me. “The question is, what would they intend to use that status for?” Earlier this week, after Morales announced that he would be meeting with Trump in Washington on Monday, three former foreign ministers of Guatemala petitioned the country’s Constitutional Court to block him from signing the agreement. Doing so, they said, “would allow the current president of the republic to leave the future of our country mortgaged, without any responsibility.”

The biggest, and most unsettling, question raised by the agreement is how Guatemala could possibly cope with such enormous demands. More people are leaving Guatemala now than any other country in the northern triangle of Central America. Rampant poverty, entrenched political corruption, urban crime, and the effects of climate change have made large swaths of the country virtually uninhabitable. “This is already a country in which the political and economic system can’t provide jobs for all its people,” McFarland said. “There are all these people, their own citizens, that the government and the political and economic system are not taking care of. To get thousands of citizens from other countries to come in there, and to take care of them for an indefinite period of time, would be very difficult.” Although the U.S. would provide additional aid to help the Guatemalan government address the influx of asylum seekers, it isn’t clear whether the country has the administrative capacity to take on the job. According to the person familiar with the safe-third-country agreement, “U.N.H.C.R. [the U.N.’s refugee agency] has not been involved” in the current negotiations. And, for Central Americans transferred to Guatemala under the terms of the deal, there’s an added security risk: many of the gangs Salvadorans and Hondurans are fleeing also operate in Guatemala.

In recent months, the squalid conditions at borderland detention centers have provoked a broad political outcry in the U.S. At the same time, a worsening asylum crisis has been playing out south of the U.S. border, beyond the immediate notice of concerned Americans. There, the Trump Administration is quietly delivering on its promise to redraw American asylum practice. Since January, under a policy called the Migration Protection Protocols (M.P.P.), the U.S. government has sent more than fifteen thousand asylum seekers to Mexico, where they now must wait indefinitely as their cases inch through the backlogged American immigration courts. Cities in northern Mexico, such as Tijuana and Juarez, are filling up with desperate migrants who are exposed to violent crime, extortion, and kidnappings, all of which are on the rise.This week, as part of the M.P.P., the U.S. began sending migrants to Tamaulipas, one of Mexico’s most violent states and a stronghold for drug cartels that, for years, have brutalized migrants for money and for sport.

Safe-third-country agreements are notoriously difficult to enforce. The logistics are complex, and the outcomes tend not to change the harried calculations of asylum seekers as they flee their homes. These agreements, according to a recent study by the Migration Policy Institute, are “unlikely to hold the key to solving the crisis unfolding at the U.S. southern border.” The Trump Administration has already cut aid to Central America, and the U.S. asylum system remains in dire need of improvement. But there’s also little question that the agreement with Guatemala will reduce the number of people who reach, and remain in, the U.S. If the President has made the asylum crisis worse, he’ll also be able to say he’s improving it—just as he can claim credit for the decline in the number of apprehensions at the U.S. border last month. That was the result of increased enforcement efforts by the Mexican government acting under U.S. pressure.

There’s also no reason to expect that the Trump Administration will abandon its efforts to force the Mexicans into a safe-third-country agreement as well. “The Mexican government thought that the possibility of a safe-third-country agreement with Guatemala had fallen apart because of the elections there,” the former Mexican official told me. “The recent news caught top Mexican officials by surprise.” In the next month, the two countries will continue immigration talks, and, again, Mexico will face mounting pressure to accede to American demands. “The U.S. has used the agreement with Guatemala to convince the Mexicans to sign their own safe-third-country agreement,” the former official said. “Its argument is that the number of migrants Mexico will receive will be lower now.”
