Dual nationals face a potential barrier to entry into the UK from February 25, 2026, unless they possess a British passport. This new rule, introduced by the Home Office, has sparked concern among British citizens living or traveling abroad. The change in border regulations requires all travelers to the UK to obtain permission, unless they are British or Irish citizens or fall under specific exemptions. Short-term visitors will need to apply for an Electronic Travel Authorisation, which incurs a fee of £6. The Home Office's decision has been met with criticism, particularly from those worried about British citizens being denied access to their own country. The EU citizens' group 'The 3 Million' advocates for a low-cost, one-time travel authorization, similar to Canada's system, to provide dual citizens with more flexibility and avoid the costly £589 certificate. This proposal aims to ensure British citizens' seamless travel and enhance the government's ability to manage immigration and identify potential threats.
