New rules starting 25 February require British dual nationals to show a UK passport or a special "certificate of entitlement" costing nearly £600 when entering the UK. Campaigners say this is "discriminatory" against women who hold second passports from Greece or Spain. The problem lies in strict name-matching rules. In Greece, women often keep their maiden name after marriage, but UK passports use their husband's name. In Spain, dual nationals have two surnames on ID, but UK passports show only one. This mismatch is causing travel issues. Julia Cross from British in Greece said, "It is causing huge problems. Many didn’t know they had to get a second passport but the requirement for name alignment on the two passports is discriminatory and only impacts women." The UK Home Office allows exceptions if people prove they can’t change their foreign passport names. Still, many women report confusion and stress due to poor communication of the new rules. Cross urged the government to set a three-month transition period to help Britons abroad adjust. She added, "I’ve had one woman say she feels banned from entering her own country." The official guidance warns, "You may not be able to board your transport to the UK without a valid document" after 25 February. Airlines risk fines if they let travelers board without proper papers. Stefanie, a British woman in Spain for 25 years, noted Spain doesn’t officially accept dual nationality after naturalisation. Many secretly keep British passports but fear showing them at airports due to name rules and possible loss of Spanish nationality. The UK’s rule change forms part of efforts to improve border immigration data. From 25 February, foreign nationals must get an electronic visa costing £16. Dual nationals cannot use this visa on their non-UK passports. Irish passport holders are exempt. Gabrielle Mordy in Australia shared that she learned of the rule only in January. The certificate of entitlement can take up to eight weeks to get, causing issues for travelers with short notice. One woman in Germany said, "They are treating tourists better than their own citizens. Why can’t we just have an ETA? Why do we have to fork out nearly £600 if we can’t get a passport? For a family travelling at Easter that is a lot of money." Some names have been changed.
