Advocates warn that tens of thousands of migrant children who came to the United States alone could lose legal representation in immigration court and increase their risk of deportation as the Trump administration allows a contract with legal services providers to expire.

Friday marks the last day of a contract under which the federal government pays for legal services for children who enter the U.S. without a parent or guardian. The government contracts out those services to a network of nearly 100 legal groups across the country that provide services to roughly 20,000 children.

The Trump administration did not immediately respond to a request for comment on why it was allowing the contract to expire. But it comes as the administration has redoubled its efforts to achieve its policy of mass deportations, and after migrant children became a target for removal from the country during the first year of President Donald Trump’s second term in office.

As part of the expiring contract, the legal groups can enter government-funded shelters and give presentations to children about their legal rights, and directly represent the children as they go through immigration court proceedings.

But as that contract ends, the providers say it’s unclear what will happen come Monday or whether they'll be able to visit their clients in the shelters where they live.

“We have no understanding of what’s going to happen to those children come next week. We don’t know if they’re going to have legal representation. The government as of yet has not identified who will take over this representation,” said Melissa Lopez, the executive director of Estrella El Paso, during a news conference earlier this week. The organization currently represents 243 unaccompanied children in western Texas and New Mexico.

The providers say their ability to enter the shelters, check on their clients and give presentations to new arrivals serves as an important oversight measure for a vulnerable population. The providers warn that without a lawyer to assist them in court and help them navigate the complexities of immigration law, children will be much more likely to be deported back to countries they initially fled.

“The government is trying to eliminate our work in this program because they know that without attorneys children will be deported,” said Lopez.

Health and Human Services, which is responsible for caring for unaccompanied migrant children while they are in government care and which administers the contract, did not respond to a request for comment Friday.
