Three emergency shelters housing an influx of children from Central America who entered the US illegally will be closed in the upcoming weeks.
The US health agency, which manages the shelters, says fewer children were crossing the border and they were adding capacity in standard shelters.
More than 57,000 children have crossed the southwest US border since October.
Efforts to increase resources in response to the crisis have so far failed in Congress.
Both the House and Senate have rejected a $3.7bn (£2.2bn) funding request from President Barack Obama, creating their own competing bills about how to respond.

The three shelters, all on US military bases, were holding unaccompanied children under a 2008 law requiring minors from countries not bordering the US be handed over to the Health and Human Services Department (HHS) with 72 hours of being caught by US border officials.
The young migrants are usually held in shelters, many run by non-profit groups, until a relative or other sponsor in the US can be found to house them while they await a deportation hearing.
