The Home Office has warned that British citizens living abroad risk being refused entry to the UK from February 25 unless they have a valid British passport.
The new border control rules come into force for the first time in 65 years of modern immigration policy.
Under these new rules, everyone traveling to the UK will need permission to enter, unless they are British or Irish citizens or otherwise exempt.
While visitors must apply for a £16 electronic travel authorization, dual nationals face a more complex requirement: they must present a British passport or pay £589 for a “certificate of entitlement” attached to their second nationality passport.
Citizens naturalized in another country, especially in the EU after Brexit, could be excluded from their own country.
A Home Office spokesperson said the digitization program enables a “seamless travel experience” while giving the government greater authority to “detain those who pose a threat.”
The 3 million campaign group has called on the government to introduce a low-cost travel authorization similar to Canada’s system, warning that British citizens risk being “locked out of their own country”.
