Dual Nationality: Can You Keep Your Original Citizenship?

A common worry before applying to become British is: will I have to give up my current citizenship? The good news is that the UK allows dual nationality. But the full answer depends on both countries, so it is worth understanding clearly. For the wider picture, see our overview of how to apply for British citizenship.

The UK side: dual nationality is allowed

The UK allows you to be a dual national (and even hold several nationalities). On the UK side, becoming a British citizen does not require you to give up any citizenship you already hold. You can become British and remain a national of your original country as far as UK law is concerned.

The other side: your country of origin decides

This is the part that catches people out. Whether you actually keep your first citizenship depends on the laws of your other country, not the UK:

• Some countries allow dual nationality — you keep both.
• Some countries do not — they may automatically withdraw your citizenship when you naturalise as British, or require you to renounce it.

Before you apply, check the rules of your country of origin, for example with its embassy or consulate. This is especially important if keeping your original nationality matters for property, inheritance, pensions or travel back home.

Practical points

• If both countries allow it, you can hold two passports and use each where appropriate.
• Some countries expect their citizens to enter and leave on that country's passport.
• Rules can change, so check current guidance from both governments before you decide.

Becoming British does not have to mean choosing between two identities. But the decision is easier when you know exactly what your other country allows.
