minimum time out of china
Hello i am traveling to Korea for the day as it is close to where my husband works, is there a minimum of time before you can return back to mainland China? I understood you only need be out for a couple of hours then you can return, I have 2 and a 1/2 hours in Seoul before i return on my flight.
Can anyone please confirm a limit or not? I have a valid multi entry visa L and still have around ten days till duration expires.
