Hi there, myself and my boyfriend are flying from London to Hanoi on the 4th November, but then plan to be in China mid December as we have some friends there.

We have one way flights as we are bringing our bicycles with us for the trip, as we plan to travel back to London by land.

Is it still possible to get a visa for china without a return ticket as we have alternative travel arrangements?

Also what is the cost? Is it better to get it in London before we go?

Thank you very much,
