Around 200 foreigners, from Uzbekistan, Kazakhstan, Pakistan and India, who were deported from the United States, will remain in Costa Rica for up to six weeks while their repatriation procedures are processed, President Rodrigo Chaves-Robles announced on Wednesday.

The first group of 135 migrants, including at least 50 children, is scheduled to arrive at Juan Santamaría International Airport at 4:30 p.m. Thursday on a flight operated by Alaska Airlines, which is being funded by the U.S. government.

Originally, their arrival was planned for Wednesday, but the flight schedule was later adjusted.

They will then be transferred by police to the Temporary Migrant Care Center (Catem) in Corredores Canton, Puntarenas Province, and remain there until their extradition process to their home countries is completed.

Costa Rica has agreed to cooperate with the U.S. in assisting with the deportation of undocumented immigrants who were detained and are in the process of returning to their respective countries.

The agreement to temporarily house deported migrants is part of a humanitarian cooperation effort with the U.S. “The United States requested our assistance in receiving 200 migrants, as they are unable to process such a large number of people at once,” Chaves said.

Public Security Minister Mario Zamora reassured the public that none of the migrants pose a security threat to Costa Rica. “None of them have pending criminal charges or any links to terrorism,” he stated.

The transportation and maintenance costs for the deportees will be covered by the U.S. government, with oversight from the International Organization for Migration.

Costa Rica became the third Central American country to accept deportees from the United States. Panama and Guatemala previously reached similar agreements during U.S. Secretary of State Marco Rubio’s recent Latin American tour.

In early February, Rubio addressed key regional issues during his visit to Costa Rica, including international aid, migration, drug trafficking, cybercrime, and China's growing influence in the region.

The United States' estimated 11 million undocumented migrants, most of them come from Latin America.

On his first day in office, President Trump declared a national emergency at the southern U.S. border and vowed to deport "millions and millions" of migrants.

Last week, Costa Rica agreed to accept migrants deported by the United States.
