My wife and I are visiting Sanya (Hainan) in November for one day, on a cruise ship. There's some debate whether we need a Chinese visa or not, but we will apply for one anyway. We both live in Northern Ireland but each have both Irish and British passports. Can we apply for visa from Dublin (as we have Irish passports) or would we both have to be living in the Irish Republic? Or will it prove easier to apply for visas by post from London, using our British passports?
