“Papers – and proof of funds – please.” Among the many Brexit consequences negotiated on the nation’s behalf was for British passport holders to become “third-country nationals” in the eyes of the European Union. This is the same status as citizens from the US, Australia, Venezuela and many other countries.
The big difference: there are far more British visitors to the EU – and wider Schengen area – than all other nationalities put together. But all third-country nationals are obliged to meet two sets of conditions when crossing the border: the general Schengen area requirement, and the individual nation’s own rules.
