Twenty international students at the University of Sussex in England have been banned from taking final exams because they have fallen behind in their tuition payments.

More than 150 Sussex students staged a protest against the decision late last week. The president of the university’s student union described the proposed payment schedules and the timing of the university’s action as unreasonable.

The protest follows a successful Facebook campaign on behalf of one of the students, Luqman Onikosi of Nigeria. When Onikosi’s sponsor in England died, he was unable to raise the money to pay the fees himself.

The university recently agreed to allow Onikosi to take his exams and put off payment until September.

Update: A follow-up protest is planned for this Friday, May 9.
