In the shadow of a huge crucifixion, workers and construction workers in the Mexican border city of Sidad Juarez are building their own small town. A tent town.
At the old fairs, under an altar built for a liturgy by Pope Francis in 2016, the Mexican government is preparing for thousands of deportes who expect to arrive from the United States in the coming weeks.
Juarez is one of the eight borderlines along 3000 kilometers (1900 miles) border, where Mexico prepares for the expected influx.

Men with boots and baseball hats climb the top of a huge metal structure to cover themselves on a thick white tarpaulin, raising elementary shelter for temporary accommodation of men and women, just like them.
Random workers, home workers, kitchen staff and farm workers are likely to be among those sent to the south soon after what President Donald Trump calls “the greatest deportation in American history.”
In addition to the protection against natural elements, deportes will receive food, medical care and assistance in receiving Mexican identity documents within the framework of a deported support program, which the President Claudia Sinbaum administration calls “Mexico hugs you.”
“Mexico will do everything he needs to take care of his compatriots and devote what is needed to accept those who are repatriated,” said Mexican Interior Minister Rosa Islala Rodriguez on Trump's inauguration day.
President Shainbaum, for his part, stressed that her government would first take care of the humanitarian needs of the returning people, saying that they would be eligible for her government's social programs and pensions and would immediately have the right to work.
She urged the Mexicans to “keep calm and cool” about relations with President Trump and his administration in a broader plan-from deportations to threat from duties.
“With Mexico, I think we are going very well,” President Trump said in a video address to the World Economic Forum in Davos this week. The two neighbors can still find a working immigration solution, which is acceptable for both of them – President Shainbaum said the key is dialogue and maintaining the communication channels open.

Undoubtedly, however, she is aware of the potential stress that the declaration of emergency on the border with the United States by President Trump can create for Mexico.
Approximately 5 million Mexicans without documents currently live in the United States and the prospect of mass return can quickly saturate and conquer border cities such as Juarez and Tijuana.
This is a problem that bothers Jose Maria Garcia Lara, Director of the Migrant 2000 Migrant shelter in Tijuana. As he takes me out of the facility, which is already approaching his capacity, he says there are very few places where he can hold more families.
“If necessary, maybe we can accommodate people in the kitchen or library,” he says.
However, there is a moment when there is simply no room – and donations from food, medical supplies, blankets and hygiene products will be too thin.
“We are hit on two fronts. First, the arrival of Mexicans and other migrants running away from violence, “says Mr Garcia.
“But we will also have mass deportations. We do not know how many people will cross the border, needing our help. Together these two things can create a huge problem. “

In addition, another key part of Mr. Trump's executive orders includes a policy called “Stay in Mexico”, according to which immigrants awaiting dates to bring their asylum cases in an American Immigration Court will have to stay in Mexico before those Appointments.
When “staying in Mexico” was in force before, during the first term of Trump and under the presidency of Andres Manuel Lopez Obrador in Mexico, the Mexican border cities struggled to cope.
Right -off groups have also repeatedly condemned the risks to which migrants are exposed, forced to wait in dangerous cities where drug cartel crime is widespread.
This time, Shainbaum made it clear that Mexico did not agree with the plan and would not accept non -mexic -seeking asylum from the United States as they were waiting for their asylum hearing. It is clear that “Stay in Mexico” only works if Mexico wants to comply with it. So far, it has drawn a trait.

President Trump has deployed about 2,500 soldiers on the southern border of the United States, where they will be charged to fulfill some of the logistics of his repression.
Meanwhile, in Tijuana, Mexican soldiers help to prepare for the consequences of it. Authorities have prepared an event center called “Flamingo”, with 1800 beds for the returning refugees and the soldiers who deliver provisions, have kitchens and showers.
As President Trump signed executive orders on Monday, the van passed through the gates of the Chapal Border Point between San Diego and Tijuana, carrying a handful of deported.
Several journalists had gathered to try to talk with, apparently, the first deported from the Trump era. However, it was just a routine deportation that was probably being prepared for weeks and had nothing to do with the documents Trump signed before the applauding crowd in Washington.
Still, symbolically, while the van whispered past the waiting media to the government -ruled shelter, they were the first of many.
Mexico will have a lot of work to accept, accommodate them and find a place in a nation that some have not seen since they left as children.
