Wanna visit my girlfriend in China , Shanghai ? May I know how long can I stay there ?

Jasper, you need to apply for an L type entry permit at the CVASC office. It takes four working days to process it in normal cases. You can ask your girlfriend to send you an invitation letter, so that you don't need to show the air tickets when submitting the L type. The stay length on the L type ranges from 30 days to 90 days. The consularr officer will decide how long it is according to your situation.
