The Government has discussed mobility arrangements across a number of areas as part of negotiations on our future relationship with the EU, and these discussions are ongoing.
The EU has already legislated such that UK nationals will not need a visa when travelling to the Schengen area for short stays of up to 90 days in any 180-day period. This will apply from the end of the transition period to all UK nationals travelling to and within the Schengen area for purposes such as tourism.
This is the standard length of stay that the EU provides to the nationals of eligible third countries that offer visa-free travel access for EU citizens, in line with existing EU legislation.
As things stand, stays beyond the EU's 90/180 day visa-free allocation from 1 January 2021 onwards will be for individual Member States to decide and implement through domestic entry rules and visa arrangements for non-EU citizens. UK nationals will need to discuss the specifics of their situation with the relevant Member State authorities and should be prepared to provide any extra documentation that may be required.
