It Is Expected That The Immediate Family Will Move In Soon
For the most part, the White House expects the President’s close family members to follow him to the new residence as well. Unless it’s a youngster away at boarding school or for a valid cause, it’s quite unusual that a family member does not move in.
It’s not necessarily ideal for a President with young children to move into the White House, but it’s a longstanding custom in the United States. In contrast, Melania Trump and her son Barron remained to reside in their Fifth Avenue penthouse in New York City as Barron completed his education, breaking a long-standing practice.
