I am in Shenzhen now and need to leave China for a fresh visa application before coming back for another two months. I have seen mixed reports about whether Hong Kong is still straightforward for this if you are applying as a foreign tourist and not a resident there.
If you have done this in the last few months, how many business days did it take, and did they ask for hotel bookings or onward flight proof from Hong Kong? I am trying to decide whether to stay in Tsim Sha Tsui for a week or just fly somewhere else and avoid the uncertainty.
