Resuming British Citizenship After Renunciation
What you need to know
- •You can resume citizenship after renunciation by making a declaration.
- •The first resumption is generally a right; subsequent ones are discretionary.
- •No Life in the UK test or English language requirement for resumption.
- •You become a citizen again from the date the declaration is registered.
- •Dual citizenship is permitted, so you may not need to give up other nationalities.
British citizens who renounced their citizenship can apply to resume it. The first resumption is generally a right, while subsequent resumptions are discretionary. The process is simpler than naturalisation and does not require the Life in the UK test.

Why People Renounce Citizenship
People renounce British citizenship for various reasons, most commonly because another country required them to give it up to acquire that country's citizenship. Some countries do not allow dual citizenship, so people were forced to choose.
Circumstances change. The country you moved to may have changed its dual citizenship laws, or you may wish to return to the UK and re-establish your status. The resumption process allows you to reclaim your British citizenship.
Eligibility
You may be eligible to resume British citizenship if:
- You were previously a British citizen (by birth, descent, registration, or naturalisation).
- You formally renounced your citizenship by making a declaration of renunciation that was registered by the Home Office.
- You have not already resumed citizenship once before (the first resumption is a right; subsequent ones require the Home Secretary's discretion).
If you lost British citizenship through other means (such as deprivation), the resumption process does not apply. Different rules govern those situations.
How to Apply
- Complete Form RS1, the declaration of resumption of British citizenship.
- Provide your original certificate of renunciation.
- Include proof of your identity (passport, birth certificate).
- Pay the application fee.
- Submit the application to the Home Office.
You can download the form from GOV.UK. The application is submitted by post, not online.

What Happens After Resumption
When your declaration is registered, you become a British citizen again from that date. You can then:
- Apply for a British passport
- Live and work in the UK without visa restrictions
- Access the NHS and public services as a British citizen
- Vote in UK elections
- Pass citizenship to your children (subject to specific rules about citizenship by descent)
The UK allows dual citizenship, so you do not need to give up any other nationality you hold when resuming British citizenship.
Second Resumption
If you have already resumed British citizenship once and then renounced it again, a second resumption is not automatic. It requires the Home Secretary's discretion. Factors considered include:
- The reasons for the second renunciation
- Your connection to the UK
- Whether allowing resumption is in the public interest
Children and Resumption
If you resume British citizenship, this does not automatically make your children British. Their citizenship depends on their own circumstances, including when and where they were born and your status at the time of their birth. See our guide on children born abroad for more information.
Next Steps
If you previously renounced British citizenship and wish to resume it, obtain Form RS1 from GOV.UK. Locate your original certificate of renunciation and prepare your identity documents.
