What is Dual Citizenship?

Dual Citizenship is when a person is regarded as a citizen of multiple countries. To have a second citizenship the laws of both your home country and the other country you intend to have citizenship must allow it as some countries don’t allow dual citizenship. However, many countries do allow multiple citizenships, including the US and the United kingdom. This means that citizens of the United States who wish to become a citizen of the United Kingdom can still maintain their US nationality as a dual national.

Having UK Dual Citizenship allows you to keep the same status in the US while enjoying the same freedoms in the United Kingdom. This means you will have the right to live, work, rent and buy assets and travel between the two countries with ease.

Rights of Dual Citizens?

Dual citizenship can be beneficial for many reasons, including having access to greater global mobility and improving your quality of life. By holding dual British-American citizenship you will be entitled the same rights as both US and UK citizens. This means that with dual citizenship you will be able to live and work in both countries. Dual citizens are also able to get access public benefits if they are entitled to them and will have the right to study in either country as well as vote in their elections.

Once you have become a British Citizen you will also be able to apply for a UK passport that you can use to travel freely in and out of the UK. Individuals who hold British dual nationality will also have access to the UK’s National Health Service (NHS).

It’s worth noting that US citizens who have dual citizenship with another country are still required to pay US taxes even whilst they are not currently living as a permanent resident in the US. Persons who hold dual British citizenship also cannot access diplomatic help from the British government when they are in their home country. This means that the UK government cannot offer help to US citizens with a second British Citizenship whilst they are in the US.
