Anne Sacoolas left the UK after the crash in Northamptonshire which killed the 19-year-old in August.
The family's campaign has attracted interest on both sides of the Atlantic due to the chief suspect being the wife of a US diplomat stationed in the UK.
Charlotte Charles and Tim Dunn said after their meeting with Mr Trump in the Oval Office that there had been "a little bit of progress".
The teenager's parents said they had refused to meet Mrs Sacoolas who was also in the White House on Tuesday.
