Anne Sacoolas will face Westminster Magistrates' Court charged with causing 19-year-old Harry Dunn's death by dangerous driving.
The 44-year-old US citizen is expected to appear by video link on January 18.
Mrs Sacoolas is charged with killing the teenager in a crash outside US military base RAF Croughton in Northamptonshire in August 2019.
She had diplomatic immunity asserted on her behalf by the US government following the collision, and was able to leave the UK 19 days after the incident.
But the Crown Prosecution Service reached the decision to charge Anne Sacoolas with causing Mr Dunn's death by dangerous driving in December 2019.
Mr Dunn's mother, Charlotte Charles, said her family were feeling "very emotional" after hearing the news.
