Urgent Warning for Dual Nationals as New UK Border Controls Approach
London, 13 February 2026 – The Home Office has confirmed significant changes to border entry requirements that will impact dual nationals starting later this month. As the UK transitions to a more digitalised border system, including the expansion of the Electronic Travel Authorisation (ETA) scheme, travellers are being urged to ensure their documentation is compliant to avoid being denied boarding.
New Restrictions for Dual Nationals
In a major policy shift effective from 25 February 2026, dual nationals who do not hold a British passport will be denied entry to the United Kingdom unless they possess a specific “Certificate of Entitlement”. This certificate, which costs £589, must be attached to the individual’s second nationality passport to prove their right of abode in the UK.
This move comes alongside the final phases of the UK ETA rollout. While American citizens were required to start applying for ETAs in early 2025, the US Embassy has issued an urgent warning this week regarding the 25 February 2026 deadline, noting that dual citizens and those in transit may face unexpected “transit traps” if their paperwork is not in order.
Applying for Your First British Passport
For those seeking to avoid these complications by obtaining their first adult British passport, eligibility remains strictly tied to British nationality. Holding nationality does not automatically guarantee the issuance of a passport; applicants must meet rigorous identity and residency criteria.
Recent reports from applicants indicate that while the process can be efficient—with some interviews being approved within minutes—the preparation of documents is vital. First-time applicants typically need to provide a full birth or adoption certificate, along with evidence of their parents’ British claim, such as a parent’s UK birth certificate or Home Office naturalisation documents.
Key Passport and Citizenship Requirements
The following table outlines the standard requirements for those seeking British citizenship or their first passport as of February 2026.

| Mandatory Tests | Life in the UK Test and a recognised English language qualification. |
| First Passport Documents | Original birth certificate and proof of British citizenship. |
| Dual National Entry Fee | £589 for a Certificate of Entitlement (if no UK passport is held). |
Frequently Asked Questions
Can I enter the UK with my foreign passport if I am also a British citizen?
From 25 February 2026, dual nationals will require either a British passport or a Certificate of Entitlement affixed to their foreign passport to enter the UK. Failure to produce these may result in being denied entry at the border or by the carrier.
How long does a first-time passport application take?
While HM Passport Office (HMPO) processing times vary, recent “real-world” data from February 2026 suggests that some straightforward applications are being processed in as little as 11 days, though overseas applications and those requiring additional document verification can take significantly longer.
What is the “One Login” system?
As of 9 February 2026, the government has introduced the “GOV.UK One Login” for new customers. This is part of a broader digital transformation to streamline how citizens access government services, including HMRC and eventually passport-related identity checks.
