Citizens of some countries, including China, India, Nigeria, Iran and Russia usually require an Irish visa. A Schengen visa is not valid for Ireland as Ireland does not belong to the Schengen area. Neither is a UK visa valid in Ireland. Please refer to https://www.dfa.ie/travel/visas/visas-for-ireland/ for details. You may request an invitation letter from Conference Partners, once you have registered. Please be sure to apply well in advance, as the process may take several months.
