Natasha Cochrane De La Rosa was born in Islington, grew up in London, pays taxes and has voted in British elections her entire adult life. None of that was enough to get her back into the country where she was born.The 26-year-old has been stranded abroad since 6 April after being denied boarding on her return flight from Amsterdam to Luton. She had cleared check-in, security and passport control without any issue. It was only at the gate that airline staff called immigration and told her she could not board because she did not have the correct documentation under the new UK border rules that came into force in February 2026.
What the new rules say
The Home Office introduced changes on 25 February 2026, stating that dual nationals can no longer enter the UK using only a foreign passport. All British citizens travelling to the UK must now present either a valid British passport or a digital certificate of entitlement. The government said public information about the change had been available since October 2024 and that a communications campaign had been running since 2023.
Why Natasha fell through the gaps
Natasha has a British father and a Spanish mother. Her parents were not married when she was born in 1999, which meant her father could not automatically pass on his British citizenship to her. She describes herself as being in a legal grey area as a result. She holds dual nationality but does not have a British passport and has previously travelled using her Spanish one without any problem.She now has two options to get home. She can apply for a British passport or pay £589 for a digital certificate of entitlement. Both require documentation proving her mother had free movement rights in the UK at the time of Natasha’s birth. Her mother never received formal paperwork confirming this and tracking down documents from 26 years ago has proven extremely difficult. Natasha said she has been told the process could take anywhere from three months to a full year to resolve.After being turned away from her Amsterdam flight, she booked a last-minute connection to Seville and is now staying with a family friend in Spain. She said she was fortunate to have somewhere to go and someone to stay with, but pointed out that many people in her situation would not have had that option.
“The government failed dual nationals”
Natasha said she takes some responsibility for not checking the rules before she travelled but argued that after 26 years of moving through borders without any issue, she had no reason to expect anything had changed. She said people have been contacting her on social media after seeing her story to say they would have faced the same situation had they not come across it first.She said the system is poorly designed and offers no support for British citizens who do not fit neatly into the standard categories. After Brexit in 2021, her mother applied for and was granted settlement papers. Her younger sister, born in Spain, was also granted papers. Natasha was told at the time that she did not qualify because she was already considered a British citizen. That status has now left her unable to get home.The Home Office said the rules apply equally to all British citizens regardless of their other nationality and are consistent with the approach taken by countries including the United States, Canada and Australia.
