Cecilia Chang was charged with forced labor Thursday in federal court in New York.
Prosecutors say Chang told students they'd lose their scholarships unless they cooked, did laundry and cleaned for her.
One student claimed he was forced to drive Chang around town, take out garbage and shovel snow.
State authorities accused Chang this month of stealing a $250,000 donation sent to the school from a charity run by a Saudi prince.
Chang, once the dean of the Institute of Asian Studies, worked at the school for 30 years.
Her lawyer did not immediately respond to a message.
