A former administrator at St. John’s University accused of embezzling about $1 million from the college in Queens has now been charged with far more lurid crimes: forcing students to clean, cook and act as her personal servants to keep their scholarships.

The ex-administrator, Cecilia Chang, who served as a dean and vice president at the university, was charged with forced labor and bribery, according to a complaint made public by federal prosecutors on Thursday.

As the dean of the Institute of Asian Studies at St. John’s, Ms. Chang had the authority to grant 15 scholarships a year. The recipients, most of whom were from overseas, were told they had to work 20 hours a week under her supervision.

The students thought they would be doing work related to the university. Instead, according to the prosecutors, she forced them to perform menial tasks at her home in Jamaica Estates, Queens.
