The White House on Tuesday will request $3.8 billion from Congress in emergency funding to deal with an influx of unaccompanied minors from Central America, a far higher amount than the Obama administration had previously signaled, according to a Capitol Hill source familiar with the plans.

The money would go to several federal agencies, including the Departments of Justice, Homeland Security, State and Health and Human Services. Funds would be allocated to send more immigration judges to the southern border, build additional detention facilities and add border patrol agents, said the source, who spoke on condition of anonymity because the administration had not formally made the request.

Administration officials had previously said that they would be requesting more than $2 billion to help stem the recent surge of women and children from El Salvador, Guatemala and Honduras. More than 52,000 unaccompanied minors and 39,000 women with children have been apprehended on the southern border this year, far more than in past years.
