The AFF Overseas team is aware that some families are being caught out by passport and immigration requirements when travelling on leave.
MOD financial and administrative support is available in certain circumstances, such as accompanied overseas assignments or return postings to the UK. But keeping passports valid for leisure travel remains a personal responsibility and a personal cost. Understanding the latest rules can help you avoid disruption and unnecessary stress.
Heading to Europe
Since 12 October 2025, British citizens travelling to countries within the Schengen area are subject to the EU’s new Entry/Exit System (EES). This replaces the manual passport stamping process with a digital system. As a result of this, families should allow extra time at the border. You will need to register your biometric details, such as fingerprints and a photograph, on first entry.
If you’re travelling via the Port of Dover, Eurotunnel at Folkestone, or Eurostar from St Pancras, these checks will take place before departure from the UK. Once registered, your EES record is valid for three years.
Families should also remember the 90/180-day rule: you can stay in the Schengen area for a maximum of 90 days within any 180-day period. On exit, you may again be asked to provide biometric confirmation. Passport validity rules are being strictly enforced in Schengen countries.
Your passport must:
- Have an issue date within the last 10 years
- Be valid for at least three months after your planned departure date from the EU.
Children must have their own passport (and visa if required). You should remain cautious of unofficial websites as future systems are introduced. The European Travel Information and Authorisation System (ETIAS) is expected later in 2026, and applications should only be made through official EU channels when it launches.
Changes for dual national families
New rules are also affecting families returning to the UK. First introduced in 2023 but being strictly enforced now, these changes affect dual nationals and children born abroad. Key requirements include:
- British dual nationals must enter the UK using a valid British passport
- Those without one must apply for a Certificate of Entitlement to prove their right of abode.
From 25 February 2026, these rules also apply to dual nationals from non-visa countries, under updated Electronic Travel Authorisation (ETA) guidance. Families with children born overseas who have not yet applied for a UK passport may face delays or be denied boarding if documentation is not in place.
Emergency travel documents
Emergency travel documents are only issued in genuine emergencies and cannot be used for routine or planned travel. These are limited to situations such as an unexpected birth, urgent medical treatment or the funeral of a close relative.
By checking passports early, understanding new systems like EES, and ensuring the correct documentation for all family members, you can focus on enjoying well-earned time together.
