And that means the ones we start planning during the next academic year. Obviously those trips entirely within the UK or entirely outwith the EU will not be affected. But for those, and I imagine it's a large number of trips each year to destinations in other EU countries, it looks as though there could be a greatly increased burden for the organisers. 1. Will the ability to use group passports continue? 2. Will the ability to include non-EU/non-UK citizens in a group by means of a List of Travellers continue? 3. Might each participant need to complete an electronic visa-waiver such as that now required by the USA? And most important, do we imagine that anybody presently negotiating even knows there might be a problem?
