I'm a UK passport holder and have to go to Shenzen for one day next week. Does anybody know if I can just get a Shenzen visa at the Lo Wu boarder crossing? Has anybody done it recently. I don't really want the bother of applying for a China visa for my passport, but I worry about turning up at Lo Wu on the day and not being able to get one. The rules seem to keep changing, as far as I can make out.
