The Pentagon confirmed on Monday that two Texas military bases will be used as temporary camps to house the immigrants.
But Defence Secretary Jim Mattis did not specify whether the facilities - Fort Bliss and Goodfellow Air Force Base - would house migrant families together.
US media earlier reported that one of the bases would be used to house migrant families and the other would shelter undocumented children who enter the US unaccompanied by an adult.
Meanwhile, US Attorney General Jeff Sessions talked tough on immigration at a school police officers' conference in Reno, Nevada, on Monday.
America's top law official said that refusing to prosecute adults who illegally enter the US "would be a disservice to the people of this country", reports the New York Times.
He told the audience that lax border enforcement would "encourage more adults to bring more children illegally".
However, he also said the Trump administration would "do everything in our power to avoid separating families".
