To Surrender UK Citizenship and take Indian Citizenship back

To apply for Indian citizenship, you will need to submit some of the essential documents, which are: proof of Indian citizenship, a valid birth certificate, and a certificate of renunciation of UK citizenship.

To surrender your UK citizenship, you need to fill out the Form RN1, which is the official form for the renunciation, then upload all the documents with the form and submit it to the UK Home Office with all the fees, then you will get a certificate of Renunciation of UK citizenship.

Since you've been living in India for the past 10 years, hold UK citizenship (acquired in 2015), and still have a valid OCI (linked to your now-expired UK passport), here’s a quick summary of how you can move forward with renouncing your UK citizenship and applying to become an Indian citizen again:

1. Apply for Indian Citizenship First

You’ll need to apply under Section 5(1)(f) (if you were previously Indian) or Section 6 (naturalisation), depending on your case. Given your long-term residence, you may qualify. Processing can take 6–12 months or longer, so it’s best to get this started early.

2. Renounce UK Citizenship (Carefully)

Once your Indian application is in progress, you can apply to renounce UK citizenship using Form RN via the UK government website. Your expired passport is okay-just make sure you include your naturalisation certificate or other proof of citizenship.

3. Surrender Your OCI Card

Once Indian citizenship is approved (or your UK renunciation is accepted), you’ll need to surrender your OCI, since it only applies to foreign citizens of Indian origin.

A Few Things to Keep in Mind:

• If you used your Indian passport after getting UK citizenship, there could be penalties-best to clarify upfront.
• You could be temporarily without a valid passport if the timing isn’t managed well, so plan accordingly.
• Consider consulting a legal expert to help coordinate both processes smoothly.
