Yes, you can. If you require a multiple-entry student visa invitation for Beijing, please let us know in advance so we can issue the documents accordingly. Please note though that it is up to the embassy to decide how many entries they will give you - which in our experience is not always as many as you might have applied for. It is also possible to apply for additional entries once you are in China at the Public Security Bureau (PSB) in Beijing. Whether those entries are granted however is up to the officer in charge, who again does not always approve these requests.
