“Dual nationals: prove you are British or you can’t come in”: that is the prospect facing people who have citizenship of both the UK and another country.
Millions of British citizens live abroad. An estimated 1.2 million have dual nationality and own a passport issued by their country of residence. Most live in nations whose citizens do not require a visa to enter the UK. These include member states of the European Union and wider Schengen area, as well as Australia, Canada, Japan, New Zealand, Singapore, South Korea and the US.
