Using 72 hour twice in 10 days
I am travelling from London to South Korea on business, and would like to stop in Shanghai on my way to meet with a friend – I have no business activities in China. I plan to reach Shanghai on Sat 1 June and will fly to South Korea on 2nd June in the evening or 3rd June in the morning. I will not be spending more than 72 hours in Shanghai. On the return leg of my trip from South Korea back to London I plan to stop in Shanghai again, either for 1 night on 9th June or just to transit whilst I catch a flight back to London on 10th June. I will be booking separate tickets, LHR to SHA return and SHA to ICN return, so in both cases I will have to clear immigration in Shanghai.
Please can you advise if I will be able to utilise the 72 hour transit visa exemption on both occasions as I transit in Shanghai twice, or if I will need to apply for a visa with multiple entries or 2 separate visas.
I am a British Citizen with a British passport and I live in London.
