UK LEAVING THE EU WON’T AFFECT SECOND PASSPORT HOLDERS
Saint Kitts & Nevis, Antigua & Barbuda, Dominica, Grenada, and St. Lucia belong to the British Commonwealth, an association of 53 nations united by ties to former British rule. As a second passport holder for these Caribbean countries you are still entitled to visa free travel to the United Kingdom and can remain in the United Kingdom for up to 6 months, also allows visa free travel to the Schengen states.
The Schengen Area includes 26 European countries that have abolished passport and any other type of border control at their mutual borders. It mostly functions as a single country for international travel purposes, with a common visa policy. The area is named after the Schengen Agreement. As a second passport holder you are entitled to still travel through these countries visa free.
Although Britain has left the European Union your second passport allows for visa free travel to the UK and Schengen states. The EU allows free movement of goods, capital and services between member states and is vastly different from Schengen.
The departure from the UK European Consumer Centre will not take place immediately. It is a long process that could take more than a year to finalize, so it won’t affect your future travel plans.
