If you have extended your study or your limit of stay is shorter than the normal duration of your study programme, you should apply for a visa extension 4 weeks before your limit of stay expires. It is the responsibility of individual students to renew their visa in a timely manner to maintain a valid and legitimate visa status throughout their study at HKU. Currently, for taught course postgraduates from the mainland, the contact office at the University is the China Affairs Office. For all other students, please contact CEDARS for visa extension.
