But the court system is clogged up and the centres short of space.
Mr Trump’s executive order directed the secretary for homeland security to expand capacity and end the policy known as “catch and release”, whereby immigrants held after crossing the border illegally are freed pending court hearings.
Now the Department of Justice has confirmed that a letter was sent requesting the deployment of extra judges. They will work from detention centres to speed up the process of determining whether asylum is granted or deportation orders should be issued.
The extra judges will be sent to locations near the Mexican border as well as other states across the US.
An estimated 11 million undocumented immigrants, many from Mexico, live in the US.
Following the executive order, new rules announced by Mr Trump’s administration last month included plans to send undocumented people to Mexico, even if they are not Mexicans, and expand the criteria for immediate deportations.
The government said the new guidelines would not usher in mass deportations, but were designed to empower agents to enforce laws already on the books.
Travel ban challenge
The ban begins on 16 March, with the White House saying it is “very confident” of winning in court.
The revised ban bars new visas for people from Somalia, Iran, Syria, Sudan, Libya and Yemen. It also temporarily blocks all refugees.
But critics maintain the revised travel ban discriminates against Muslims.
Which states have launched challenges and why?
Washington – it has “same illegal motivations as the original” and harms residents, although fewer than the first ban
New York – “a Muslim ban by another name”, said the attorney general
Hawaii – argued it would harm its Muslim population, tourism and foreign students
