There are two possibilities:

  1. The equal status was granted due to a temporary residence permit/limited leave of remain. As the time limitation expired, the equal status also expired. If you have received a new residence permit, apply for equal status again in time. 
  2. You have exceeded the standard duration + two tolerance semesters in your bachelor programme or the standard duration + two tolerance semesters in a stage of your diploma programme (see tution fee regulation for EEU/EEA/CH citizens).
