To avoid being caught out by passport and immigration requirements when travelling to Europe on leave, it can be helpful to understand the latest rules to avoid disruption and unnecessary stress.
Entry/Exit System
British citizens travelling to countries in the Schengen area are now subject to the EU’s new digital Entry/Exit System (EES). You will need to register biometric details (fingerprints and a photo) when entering the EU. Once registered, your EES record is valid for three years.
You should allow extra time at the border, particularly during peak periods.
Passport validity requirements
Your passport must have been issued within the last 10 years and be valid for at least three months beyond your planned departure from the EU. If you renewed a passport before 1 October 2018, check the issue date carefully as some may no longer meet Schengen rules.
Children and minors must have their own passport and a visa, if required.
Returning to the UK on leave
Important changes now being enforced may affect entry to the UK for some families. This applies to dual nationality partners or children and children born overseas without a UK passport.
British dual nationals must enter the UK using a valid British passport. If a British passport is not held, you must apply for a Certificate of Entitlement to prove your right of abode: Prove you have right of abode in the UK: Apply for a certificate of entitlement – GOV.UK
These rules also apply to dual nationals from non-visa countries under updated Electronic Travel Authorisation (ETA) guidance. Electronic Travel Authorisation (ETA): Guide for Dual Citizens
