School children from third countries who are resident in EU or EFTA countries will continue to be able to travel to the UK under the List of Travellers visa scheme. They do not need to obtain their own travel document or visa until 31 December 2020
This applies if the UK leaves the EU with a deal and if the UK leaves the EU without a deal.What you need to show at the border will not change. Pupils must have photographic ID or a recent photograph attached to the List of Travellers form. The List of Travellers form must be authenticated by the responsible authority in the appropriate member state to confirm the pupil’s residence status and their right to re-entry.
