I am studying in Beijing at the moment with an F type visa, however my visa runs out on the 30th of this month (August) and my flight is not until September 10th. I have been told it is possible to get a 10 day extension but that i must have residensy proof from my university, however I will not be staying at the university from the 31st onwards and want to go to hong kong in between. Is there any way to get a normal visa extension rather than a 10 day, and also if i were to go to Hong Kong would I need a visa to return go through the airport but stay in the airport and get a plane back to england? Sorry for a very long and confusing message, but I would be very grateful for any help.
