LaRose, 46, of Pennsburg, Pa., had previously pleaded not guilty to charges of helping foreign terror suspects intent on starting a holy war in Europe and South Asia.
Court records show LaRose is scheduled for a change of plea hearing in federal court in Philadelphia at 2 p.m. Tuesday.
She has been in custody since November of 2009.
LaRose, who allegedly used the online screen names "Jihad Jane" and "Fatima LaRose," had for at least a time cooperated with authorities after her arrest, a Pennsylvania congressman has said.
She is facing a potential life sentence if convicted on a charge she had agreed to kill a Swedish cartoonist who had offended Muslims.
The indictment alleges that the twice-divorced LaRose, who cared for her boyfriend's elderly father in their small-town apartment, grew obsessed with radical Islamists online and agreed to raise funds for them and recruit others before moving overseas in the fall.
Among those she allegedly recruited was Jamie Paulin-Ramirez, 31, of Leadville, Colo., a single mother who also spent long hours on the Internet before moving to Ireland with her 6-year-old son and marrying a terror suspect from Algeria the day she arrived.
